Relating physical and chemical properties of four different biochars and their application rate to biomass production of Lolium perenne on a Calcic Cambisol during a pot experiment of 79days.  

PubMed

Three pyrolysis biochars (B1: wood, B2: paper-sludge, B3: sewage-sludge) and one kiln-biochar (B4: grapevine wood) were characterized by determining different chemical and physical properties which were related to the germination rates and to the plant biomass production during a pot experiment of 79days in which a Calcic Cambisol from SW Spain was amended with 10, 20 and 40tha(-1) of the four biochars. Biochar 1, B2 and B4 revealed comparable elemental composition, pH, water holding capacity and ash content. The H/C and O/C atomic ratios suggested high aromaticity of all biochars, which was confirmed by (13)C solid-state NMR spectroscopy. The FT-IR spectra confirmed the aromaticity of all the biochars as well as several specific differences in their composition. The FESEM-EDS distinguished compositional and structural differences of the studied biochars such as macropores on the surface of B1, collapsed structures in B2, high amount of mineral deposits (rich in Al, Si, Ca and Fe) and organic phases in B3 and vessel structures for B4. Biochar amendment improved germination rates and soil fertility (excepting for B4), and had no negative pH impact on the already alkaline soil. Application of B3, the richest in minerals and nitrogen, resulted in the highest soil fertility. In this case, increase of the dose went along with an enhancement of plant production. Considering costs due to production and transport of biochar, for all used chars with the exception of B3, the application of 10tha(-1) turned out as the most efficient for the crop and soil used in the present incubation experiment.

Simulating transport of nitrogen and phosphorus in a Cambisol after natural and simulated intense rainfall.  

PubMed

Intense rainfall adversely affects agricultural areas, causing transport of pollutants. Physically-based hydrological models to simulate flows of water and chemical substances can be used to help decision-makers adopt measures which reduce such problems. The purpose of this paper is to evaluate the performance of SWAP and ANIMO models for simulating transport of water, nitrate and phosphorus nutrients, during intense rainfall events generated by a simulator, and during natural rainfall, on a volumetric drainage lysimeter. The models were calibrated and verified using daily time series and simulated rainfall measured at 10-minute intervals. For daily time-intervals, the Nash-Sutcliffe coefficient was 0.865 for the calibration period and 0.805 for verification. Under simulated rainfall, these coefficients were greater than 0.56. The pattern of both nitrate and phosphate concentrations in daily drainage flow under simulated rainfall was acceptably reproduced by the ANIMO model. In the simulated rainfall, loads of nitrate transported in surface runoff varied between 0.08 and 8.46 kg ha(-1), and in drainage form the lysimeter, between 2.44 and 112.57 kg ha(-1). In the case of phosphate, the loads transported in surface runoff varied between 0.002 and 0.504 kg ha(-1), and in drainage, between 0.005 and 1.107 kg ha(-1). The use of the two models SWAP and ANIMO shows the magnitudes of nitrogen and phosphorus fluxes transported by natural and simulated intense rainfall in an agricultural area with different soil management procedures, as required by decision makers.

Estudio del comportamiento acustico de recubrimientos de suelo derivados de la madera  

NASA Astrophysics Data System (ADS)

This work describes a study of the vibroacoustic behaviour of laminate flooring and is partly accomplished by means of an experimental method somewhat simpler than that normally used at the present time and partly by a hybrid FEM-FDTD numerical method that reproduces the proposed experiment. The experimental configuration records the sounds emitted by laminate floors when impacted and the numerical method allows the sound produced by the laminate floor to be determined before installation by previously reproducing its sound. The registers obtained from both methods are evaluated from the psychoacoustic perspective with the aim of determining the relevant parameters involved in their perception, and thus provide a method of distinguishing the effect of the different component materials on the sound produced by this type of floor covering. In the field of building acoustics, with which this work is involved, laminate flooring is seen as a good solution for deadening the noise of impacts. This question has now become important due to stricter building acoustic regulations (DB-HR Proteccion frente al ruido" del Codigo Tecnico de la Edificacion, CTE). Laminate floors possess the advantage that they can be installed over existing floor coverings. Their lightness, which adds little additional strain to structures, and the fact that they are easy to fit, make them an attractive solution at the present time and gives them promising prospects for the future. Of the different types available, synthetic laminate floors are now the most popular by far in almost all types of building and for this reason research is being carried out on the users' opinion of their quality and convenience. Among the factors that affect the latter quality is their acoustic behaviour as regards both the insulation of sound transmitted to neighbouring rooms and the sound reflected from the floor in the room in which it is installed. The conclusions reached in this work are related to the latter aspect, known as acoustic conditioning, rather than with acoustic insulation. Synthetic laminate floors are made of extremely rigid materials normally fitted over an underlay of softer material to improve thermal and acoustic behaviour and also make them more comfortable to walk on due to the underlay's shock-absorbing properties. This paper proposes a method of characterising synthetic laminate floors to provide an evaluation of the acoustic and psychoacoustic behaviour of the sound produced by the floor inside the room in which it is emitted. As has already been indicated, an experimental model is proposed to carry out tests on different combinations of synthetic laminate flooring and underlay materials. Sound registers are obtained directly from the experimental models by means of a measuring microphone and the psychoacoustic parameters that determine the acoustic qualities as perceived by human subjects are then determined. At the same time as these experiments are being carried out and analysed, a numerical model is implemented based on a combination of the finite elements method (FEM) and the finite difference in the time domain method (FDTD). This procedure is based on a finite elements 3D model with fluid-structural interaction to solve the dynamic problem caused by an impact. The velocity of each surface node is obtained from this model. By applying the method of finite difference in the time domain (FDTD), these velocities provide the sound pressure level at any point, according to the position of the microphone. This experiment enables different types of flooring to be characterised before they are fitted, provided that their mechanical characteristics (elastic modules and loss factors) are known. The subsequent processing of the sound archives obtained from the numerical experiment provides a method of identifying similarities between the results obtained from the physical experiment and those of the numerical model, thus demonstrating that it is possible to determine the acoustic quality of different types of flooring materials by numerical simulat

During soil solute transport events, preferential flow paths generate gradient concentrations between fast and slow moving regions dominated by different pore water velocities. Under stationary water flow conditions, advection and mechanical dispersion are the controlling mechanisms. Under a periodic irrigation regime, amid irrigation events, water flow decreases and solutes become more uniformly distributed through the soil regions due to diffusion.

Pot experiments were conducted in greenhouse conditions to study the effects of increasing cadmium (Cd) levels on biomass production and Cd contents in corn, (Zea mays L.), garlic (Allium sativum L.), and spinach (Spinacia oleracea L.). Plants were grown in two soil types: Eutric cambisol soil and A gleyic luvisol soil. Spinach proved to be the most sensitive to Cd treatments as its biomass considerably decreased with the increasing Cd levels. Cadmium contents of the three crops increased with increasing levels of Cd applications. Statistical differences were observed in the Cd contents of crops depending on soil type. With the same Cd rates, Cd tissue concentration of test plants grown in the strongly acidic Gleyic luvisol soil were many times higher than that of plants grown in a neutral Eutric cambisol soil. 14 refs., 4 tabs.

Influence of soil tillage and erosion on the dispersion of glyphosate and aminomethylphosphonic acid in agricultural soils  

NASA Astrophysics Data System (ADS)

Erosion processes can strongly influence the dissipation of glyphosate and aminomethylphosphonic acid applied with Roundup Max in agricultural soils; in addition, the soil structure state shortly before erosive precipitations fall can be a key parameter for the distribution of glyphosate and its metabolite. Field rain simulation experiments showed that severe erosion processes immediately after application of Roundup Max can lead to serious unexpected glyphosate loss even in soils with a high presumed adsorption like the Cambisols, if their structure is unfavourable. In one of the no-tillage-plot of the Cambisol, up to 47% of the applied glyphosate amount was dissipated with surface run-off. Moreover, at the Chernozem site with high erosion risk and lower adsorption potential, glyphosate could be found in collected percolation water transported far outside the 2x2 m experimental plots. Traces of glyphosate were found also outside the treated agricultural fields.

Ecotoxicity of benzo[a]pyrene assessed by soil microbial indicators.  

PubMed

The ecotoxicity of benzo[a]pyrene (BaP) to soil microorganisms was evaluated using the following microbial indicators: soil microbial biomass, respiration, nitrification, and Shannon index. Two soil types, udic ferrosols and aquic cambisols, were amended with 0?mg/kg, 1?mg/kg, 10?mg/kg, 100?mg/kg, 500?mg/kg, or 1000?mg/kg BaP; incubated at 25?C; and tested on days 28, 60, and 180. The Shannon index was extremely insensitive to BaP. Microbial biomass and respiration could not be classified as sensitive indicators because of their relatively high 10% effect concentration (EC10) values. Nitrification was the most sensitive indicator in both soils and could be the preferred microbial indicator for testing the ecotoxicity of BaP. Higher toxicity of BaP was exhibited in udic ferrosols than in aquic cambisols, and the ecotoxicity of BaP decreased with incubation time. Extending the 28-d incubation time, which is suggested in the International Organization for Standardization and Organisation for Economic Co-operation and Development guidelines, to 60 d was recommended for future microbial toxicity tests of BaP. On day 28, the EC10 values for microbial biomass, respiration, and nitrification were 71?mg/kg, 43?mg/kg, and 3.4?mg/kg in aquic cambisols and 51?mg/kg, 22?mg/kg, and 1.3?mg/kg in udic ferrosols, respectively. On day 60, these values were 106?mg/kg, 59?mg/kg, and 19?mg/kg in aquic cambisols and 77?mg/kg, 40?mg/kg, and 6.9?mg/kg in udic ferrosols. These values could be used in combination to derive ecotoxicological soil screening levels of BaP. PMID:25041896

Effects of soil type and genotype on cadmium accumulation by rootstalk crops: implications for phytomanagement.  

PubMed

The variations of Cd accumulation in three rootstalk crop species (radish, carrot and potato) were investigated by using twelve cultivars grown in acidic Ferralsols and neutral Cambisols under two Cd treatments (0.3 and 0.6 mg kg(-1)) in a pot experiment The result showed that the total Cd uptake was significantly affected by genotype, soil type and interaction between them, suggesting the importance of selecting proper cultivars for phytoextraction in a given soil type. Among the cultivars tested, potato cultivar Luyin No.1 in Ferralsols and radish cultivar Zhedachang in Cambisols exhibited the highest Cd phytoextraction efficiency in aerial parts (4.45% and 0.59%, respectively) under 0.6 mg kg-1 Cd treatment. Furthermore, the Cd concentrations in their edible parts were below the National Food Hygiene Standard of China (0.1 mg kg(-1), fresh weight). Therefore, phytomanagement of slightly Cd-contaminated soils using rootstalk crops for safe food production combined with long-term phytoextraction was feasible, and potato cultivar Luyin No.1 for Ferralsols and radish cultivar Zhedachang for Cambisols were promising candidates for this approach.

Changes in cadmium mobility during composting and after soil application  

SciTech Connect

The effect of twelve weeks of composting on the mobility and bioavailability of cadmium in six composts containing sewage sludge, wood chips and grass was studied, along with the cadmium immobilization capacity of compost. Two different soils were used and Cd accumulation measured in above-ground oat biomass (Avena sativa L.). Increasing pH appears to be an important cause of the observed decreases in available cadmium through the composting process. A pot experiment was performed with two different amounts of compost (9.6 and 28.8 g per kg of soil) added into Fluvisol with total Cd 0.255 mg kg{sup -1}, and contaminated Cambisol with total Cd 6.16 mg kg{sup -1}. Decrease of extractable Cd (0.01 mol l{sup -1} CaCl{sub 2}) was found in both soils after compost application. The higher amount of compost immobilized an exchangeable portion of Cd (0.11 mol l{sup -1} CH{sub 3}COOH extractable) in contaminated Cambisol unlike in light Fluvisol. The addition of a low amount of compost decreased the content of Cd in associated above-ground oat biomass grown in both soils, while a high amount of compost decreased the Cd content in oats only in the Cambisol.

Invertebrate fauna associated with Torpedograss, Panicum repens (Cyperales: Poaceae), in Lake Okeechobee, Florida, and prospects for biological control  

SciTech Connect

Torpedograss, Panicum repens L., is an adventive, rhizomatous grass species that has become an invasive weed of terrestrial, wetland, and aquatic environments in tropical and subtropical regions worldwide. Until recently, strategies for controlling torpedograss in the USA have focused almost exclusively on mechanical and chemical methods, either alone or in combination, with varied results. A survey of the arthropods and nematodes currently associated with the plant in Lake Okeechobee, Florida, was conducted as part of a feasibility study to determine whether torpedograss is an appropriate target for a classical biological control program. Overall, approximately 4,000 arthropods and 400 nematode specimens were collected. Sweep, clipped vegetation, and soil core samples were dominated by representatives of the arthropod orders Hemiptera, Hymenoptera, Diptera, and Acari. Lesion nematodes of the genus Pratylenchus were commonly associated with the roots of torpedograss. None of the organisms collected were torpedograss specialists. Although classical biological control of torpedograss is feasible based on the extent of the infestation, economic losses, resistance to conventional controls, and the report of a potentially host specific natural enemy in India, the botanical position of this grass weed will require a formal risk assessment before proceeding with a classical biological control program. (author) [Spanish] La conota, Panicum repens L., es una especie foranea de pasto que produce rizomas que ha convertido en ser una maleza invasora de ambientes terrestres, pantanosos y acuaticos en regiones tropicales y subtropicales en todo el mundo. Hasta hace un tiempo reciente, las estrategias para controlar conota en los EEUU eran enfocadas casi exclusivamente en los metodos mecanicos y quimicos, solos o en combinacion, con resultados variables. Un muestreo de los artropodos y nematodos asociados corrientemente con esta planta en el Lago de Okeechobee, Florida, fue realizado como parte de un estudio de factibilidad para determinar si conota es una candidata apropiada para un programa de control biologico clasico. En general, especimenes de aproximadamente unos 4,000 artropodos y unos 400 nematodos fueron recolectados. Muestras recolectadas pasando una red sobre vegetacion mezclada, cortando la vegetacion y tomando centros del suelo fueron dominados por representantes de artropodos de los ordenes de Hemiptera, Hymenoptera, Diptera, y Acari. Nematodos en el genero Pratylenchus, que causan lesiones sobre tejido, fueron asociados regularmente con las raices de conota. Ninguno de los organismos recolectados eran especialistas sobre conota. Aunque el control biologico clasico de la conota es factible basado sobre la magnitud de la infestacion, las perdidas economicas, la resistencia hacia los metodos de control convencionales y el informe en la India de un posible enemigo natural especifico a esta planta, la posicion botanica de este pasto maleza requiere una evaluacion de riesgo economico formal antes de continuar con un programa de control biologico clasico.

Profesionalismo: Un estudio fenomenologico sobre experiencias de universitarios en programas de salud  

NASA Astrophysics Data System (ADS)

Some studies suggest that, upon admission, medicine programs students display eagerness for community service, aspirations to be useful, and to contribute to society's well-being. Those same studies reflect that qualities of idealism, moral nature, and internal motivation, suffer a subsequent diminishing. The researchers inferred that the main reason for this process of change in the mood and disposition of these future physicians lies in the modeling they receive from medical professionals throughout clinical learning activities, by way of behavior and relationships exhibited during daily interaction with peers, patients and the students themselves. This phenomenological study used a cross-sectional sample to explore the experiences of future health workers as they went through didactic and clinical phases of their training curriculum. The study employed semi-structured interviews and reflective journals to explore those experiences and to discover the meanings ascribed by the participants. The analysis revealed that the students defined "professionalism" in terms of scientific knowledge, commitment, respect for human dignity, comradeship, courtesy, empathy, integrity, altruism, motivation. They also described their feelings as they went through the didactic and clinical experiences, and recognized as very important the extracurricular activities of community service, describing them as useful opportunities which contributed to understand their work in terms of a mission dedicated to the achievement of the social benefit. From their individual perspectives, the clinical environment could, in general, be described as congruent with those characteristics of professionalism. During the study we had the opportunity to share, in a little deeper way, the environment... the world... of this small group of young students as we went on trying to decipher their feelings and thoughts. At the end, we realized the richness of their sensibilities, we perceived the intensity of their moral and ethical convictions, we were able to understand their concerns, worries, struggles and efforts. This life event had profound and significant repercussions in our personal and professional life. As a result, and from now on, we will no longer look at our young scholars and apprentices without imagining a noble spirit, with goals which at times could seem unattainable... without completely visualizing or conceiving real hope for a better country.

Use of Physio-Hydrological Units for SMOS Validation at the Valencia Anchor Station Study Area  

NASA Astrophysics Data System (ADS)

The SMOS space mission will soil moisture over the continents and ocean surface salinity with the sufficient resolution to be used in global climate change studies. With the aim of validating SMOS land data and products at the Valencia Anchor Station site (VAS) in a Mediterranean Ecosystem area of Spain, we have designed a sample methodology using a subdivision of the landscape in environmental units related to the spatial variability of soil moisture (Milln-Scheiding, 2006; Lopez-Baeza, et al. 2008). These physio-hydrological units are heterogeneously structured entities which present a certain degree of internal uniformity of hydrological parameters. The units are delimited by integrating areas with the same physio-morphology, soil type, vegetation, geology and topography (Flugel, et al 2003; Milln-Scheiding et al, 2007). Each of these units presented over the same pedological characteristics, vegetation cover, and landscape position should have a certain degree of internal uniformity in its hydrological parameters and therefore similar soil moisture (SM). The main assumption for each unit is that the dynamical variation of the hydrological parameters within one unit should be minimum compared to the dynamics of another unit. This methodology will hopefully provide an effective sampling design consisting of a reduced number of measuring points, sparsely distributed over the area, or alternatively, using SM validation networks where each sampling point is located where it is representative of the mean soil moisture of a complete unit area. The Experimental Plan for the SMOS Validation Rehearsal Campaign at the VAS area of April-May 2008 used this environmental subdivision in the selection and sampling of over 21.000 soil moisture points in a control area of 10 x 10 km2. The ground measurements were carried out during 4 nights corresponding to a drying out period of the soil. The sampling consisted of 700 plots with 4 volumetric SM cylinders and 7 Delta-T Theta Probe measurements (with 3 repetitions each), covering the whole area. This experimental campaign permits the characterization of the soil moisture distribution within each physio-hydrological unit and results in a soil moisture map of the VAS site. All of it used for the validation of the aircraft observations done throughout the campaign. The ground measurement results obtained indicate that soil properties and vegetation cover are the parameters of the physio-hydrological units that most influence the moisture of the soil. This relationship will permit a more simple delimitation of the physio-hydrological Units and a reduction of the number of sample points for the calibration/validation of SMOS products.

Effect of long-term phosphorus fertilization on soil Se and transfer of soil Se to crops in northern Japan.  

PubMed

Phosphorus (P) fertilizer can potentially serve as a source for Se accumulation in croplands. Furthermore, it has been reported that the addition of P fertilizer to soil may enhance Se availability. Japanese agricultural soils are typically enriched in P as a result of long-term, excessive P fertilization. Therefore, we conducted a three-year field experiment in order to evaluate the effect of P fertilization on the Se content of soils and crops. Potato, wheat and barley were cultivated with and without P fertilization at two field sites in Hokkaido (northern Japan) with different levels of historical P accumulation. The first field site consisted of an Andosol soil with low available P and the second site, a Cambisol soil with high available P. The three years of continuous P fertilization over the course of the experiment did not result in a significant increase in the Se content of soils or plants. The Se content of soils and plants, however, was higher in soil samples from the Cambisol field site than from the Andosol field site, and total soil Se was significantly correlated with available soil P. Soluble soil Se and the soil-plant transfer factor for Se were not affected by P fertilization. Thus, we concluded that the higher plant Se content at the Cambisol field site was primarily due to the higher levels of accumulated Se in the soil at the site and that historical excess P fertilization typical of agricultural soils in Japan contributes to increased Se uptake by crops.

Spatial distribution and development of soils in tropical karst areas from the Peninsula of Yucatan, Mexico  

NASA Astrophysics Data System (ADS)

Better understanding of soil formation requires knowing the spatial distribution of the soils that allows constructing models of soil sequences in multiple directions along various types of gradients. This approach was applied to comprehend the soil formation from the soil distribution in the tropical karst areas of the Peninsula of Yucatan, Mexico. For soil mapping, a two-step methodology was followed. First, a geomorphic analysis was performed; subsequently, 382 soil profiles were reclassified and integrated into a geopedologic map. Additional soil survey was carried out in areas where soil information was lacking (123 soil profiles). Satellite images were used to identify flooded areas. After conducting numerous field verifications and analyses, landforms and soils were combined to make a soilscape map. Based on field observations and the soilscape map, soil development was analyzed on soil sequences. Four geomorphic environments were identified, karstic plains and hills with Leptosols, Cambisols, Luvisols, and Vertisols; coastal plains with Arenosols, Regosols, Solonchacks, and Histosols; fluvio-paludal plains with Gleysols, Histosols, Leptosols and Solonchacks; and tectono-karstic plains and hills with Leptosols, Cambisols, Luvisols, and Vertisols. Relevant soil forming factors in the Peninsula of Yucatan include time of emersion of the limestone platforms, climate, rock type, and macro- and micro-relief. Other factors such as groundwater level, fractures, also have an influence on soil formation. Karst development can be considered as a complex soil and relief forming factor. Terra Rossa soils as Leptosols, Cambisols, Luvisols, Nitisols and Vertisols in the Peninsula of Yucatan may be polygenic. In some cases, the theory of residual origin fits better the data than the theory of allochthonous origin; in other cases, it is the other way around.

Adsorption of glyphosate and aminomethylphosphonic acid in soils

The results showed that glyphosate is initially adsorbed mostly in the upper 2 cm. It is than transported and adsorbed after few days in deeper soil horizons with concomitant increasing content of its metabolite aminomethylphosphonic acid. Moreover, Fe-oxides seem to be a key parameter for glyphosate and aminomethylphosphonic adsorption in soils. This study confirmed previous studies: the analysis showed lower contents of dithionite-soluble and Fe-oxides for the Chernozem, with consequently lower adsorption of glyphosate and aminomethylphosphonic as compared with the Cambisol and the Stagnosol.

Low intensity ultrasonic vibration amplitude as a tool for characterisation water stable soil aggregates  

NASA Astrophysics Data System (ADS)

Ultrasonic dispersion of soil aggregates is a useful method to determine soil aggregate stability. Commercially available ultrasonic devices, however, operate at relatively high ultrasonic power, which hampers the analysis of less stable aggregates. Ultrasonic power is controlled in these devices with rather low accuracy and is used for correlation with the process of soil disaggregation. Self-developed ultrasonic equipment remedies these shortcomings by using low intensity ultrasonic vibrations. The vibration amplitude rather than the ultrasonic power is used to control the magnitude of loading in the dispersion experiment. Under well-defined geometrical conditions, the vibration amplitude strongly correlates with the magnitude of the acoustic pressure waves emitted into the fluid that cause disaggregation of soil particles. Samples of aggregates 2 000 - 250 ?m of a degraded loamy silt chernozem, a loamy clay cambisol and a loamy sand cambisol had been collected under different tillage regimes in Austria: conventional tillage (CT) with mechanical weed control, reduced tillage (RT) and no tillage (NT) with inter cropping in winter. The cavitation threshold of gas saturated de-ionized water was determined at an ultrasonic vibration amplitude of 0.5-0.6 m at 20 kHz frequency (acoustic pressure 0.9-1.1 bar) with a diode array spectrophotometer. Subsequent experiments were performed near this limit to be able to characterize weakly aggregated soils. Measuring soil aggregate stability (SAS) according to DIN norm showed greater aggregate stability of cambisol than of chernozem, however, could hardly show influences of tillage. Better results were obtained with the USAS (ultrasound soil aggregate stability) method, which on the one hand validated the SAS results. On the other hand it was possible to show an influence of soil tillage on aggregate stability, which significantly decreased from NT to RT and to CT for both soil types. The measurements correlated with total organic carbon content in aggregates that was greater in no tillage than in conventional tillage and larger in cambisol than in highly degraded chernozem. The data suggest that the dynamic of soil dispersion depends on the absorbed ultrasonic energy and the vibration amplitude. Promising results were obtained at ultrasonic vibration amplitudes of 0.5 ?m and 2 ?m, respectively. Dispersion experiments at 5 ?m did not allow for a differentiation between soil types nor tillage variant, which indicates that low intensity vibrations should be used to monitor differences in aggregate stabilities.

Impact of low molecular weight organic acids and dissolved organic matter on sorption and mobility of isoproturon in two soils.  

PubMed

Isoproturon is a selective herbicide belonging to the phenylurea family and widely used for pre- and post-emergence control of annual weeds. Soil amendments (e.g. organic compounds or dissolved organic matter) may affect environmental behavior and bioavailability of pesticides. However, whether the physiochemical process of isoproturon in soils is affected by organic amendments and how it is affected in different soil types are unknown. To evaluate the impact of low molecular weight organic acids (LMWOA) and dissolved organic matter (DOM) on sorption/desorption and mobility of isoproturon in soils, comprehensive analyses were performed using two distinct soil types (Eutric gleysols and Hap udic cambisols). Our analysis revealed that adsorption of isoproturon in Eutric gleysols was depressed, and desorption and mobility of isoproturon were promoted in the presence of DOM and LMWOA. However, the opposite result was observed with Hap udic cambisols, suggesting that the soil type affected predominantly the physiochemical process. We also characterized differential components of the soils using three-dimensional excitation-emission matrix (EEM) fluorescence spectroscopy and Fourier transform infrared (FT-IR) spectroscopy and show that the two soils displayed different intensity of absorption bands for several functional groups.

Impacts of afforestation on groundwater resources and quality  

NASA Astrophysics Data System (ADS)

Plans to double the proportion of land under forest cover in Ireland by the year 2035 have been initiated. The plan, primarily financially driven, ignores potential environmental impacts of forestry, particularly impacts on groundwater resources and quality. Since groundwater supplies almost 25% of Ireland's total potable water, these impacts are important. Field investigations indicate that afforestation leads to a reduction in runoff by as much as 20%, mainly due to interception of rainfall by forest canopies. Clearfelling has the opposite impact. Implications are that uncoordinated forestry practices can potentially exacerbate flooding. Groundwater recharge is affected by forestry, largely due to greater uptake of soil water by trees and to increased water-holding capacity of forest soils, arising from higher organic contents. Recharge rates under forests can be reduced to one tenth that under grass or heathland. Groundwater quality may be affected by enhanced acidification and nitrification under forests, due partly to scavenging of atmospheric pollutants by forest canopies, and partly to greater deposition of highly acid leaf litter. The slower recharge rates of groundwater under forests lead to significant delays in manifestation of deterioration in groundwater quality. Rsum. Des plans sont l'tude pour doubler la proportion du couvert forestier en Irlande d'ici 2035. Le plan, primitivement dtermin sur une base financire, ignore les impacts environnementaux potentiels de la foresterie, et particulirement les impacts sur les ressources en eau souterraine et leur qualit. Du fait que les eaux souterraines satisfont presque 25% du total de l'eau potable de l'Irlande, ces impacts sont importants. Les tudes de terrain montrent que le reboisement conduit une rduction du ruissellement d'au moins 20%, principalement cause d'une interception de la pluie par le couvert forestier. Les coupes ont un impact contraire. Les implications sont que des pratiques forestires non coordonnes sont susceptibles d'exacerber les crues. La recharge des nappes est affecte par la foresterie, surtout cause de prlvements plus importants de l'eau du sol par les arbres et cause de la capacit accrue des sols forestiers retenir de l'eau, conduisant de plus fortes teneurs en matires organiques. Les taux de recharge sous les forts peuvent tre rduits d'un dixime par rapport la prairie ou la lande. La qualit de l'eau souterraine peut tre affecte par une acidification accrue et par une nitrification sous les forts, provoques pour une part par une fixation des polluants atmosphriques par le couvert forestier et pour une autre part par un dpt plus important d'une litire plus fortement acide. Les taux de recharge plus lente des nappes sous les forts conduisent des retards importants dans la manifestation de la dtrioration de la qualit de l'eau souterraine. Resumen. Se han iniciado los planes para duplicar la proporcin de terrenos reforestados en Irlanda hacia el ao 2035. El plan, impulsado por fines econmicos, ignora los impactos potenciales medioambientales de la silvicultura, y, en particular, los impactos a los recursos de aguas subterrneas y a su calidad. Puesto que el 25 % del agua potable en Irlanda es suministrada por medio de aguas subterrneas, dichos impactos son importantes. Las investigaciones de campo indican que la reforestacin lleva a una reduccin de la escorrenta de hasta un 20 %, fundamentalmente por la interceptacin de la lluvia en las copas de los rboles, mientras que la deforestacin tiene el impacto opuesto. Las implicaciones son tales que las prcticas forestales descoordinadas pueden aumentar enormemente el riesgo de inundaciones. Tambin la recarga a los acuferos se ve afectada por la reforestacin, debido, sobre todo, al uso del agua del suelo por los rboles y a la mayor capacidad de retencin de los suelos en zonas boscosas, al disponer de ms materia orgnica.

Biotransformation of pesticides in saturated-zone materials  

NASA Astrophysics Data System (ADS)

Many studies have been conducted to evaluate pesticide contamination of groundwater in the United States, but investigations of pesticide biotransformation in saturated zones are much less numerous than in surface soils. Because results of studies using soils are not directly applicable to the subsurface, the purpose of this paper is to illustrate examples of pesticide biotransformation in saturated-zone materials. Although it must be considered with caution, the US Environmental Protection Agency's (EPA) "Pesticides in Ground Water Database" was used to focus the discussion on the biotransformation potential of dibromoethane (EDB), atrazine, acetanilide herbicides, and aldicarb, all of which have been detected in groundwater in the United States. Results of more than two dozen studies indicate that a biotransformation potential for these pesticides exists in saturated-zone materials, although for any given pesticide substantial differences in biotransformation occurred. These variations were due both to differences in experimental methods and to heterogeneities in the subsurface materials under investigation. However, because biotransformation mechanisms were not well investigated, it is generally not possible to extrapolate predictions of biotransformation potential beyond the specific sites investigated. These results highlight the need to better understand microbial genetic regulation of biotransformation processes so that genetic information may be effectively incorporated into future investigations of biotransformation potential in the subsurface. Rsum De nombreuses tudes ont t ralises pour valuer le degr de pollution des aquifres par les pesticides aux tats-Unis, mais les recherches concernant la biotransformation des pesticides dans les eaux souterraines sont beaucoup moins nombreuses que dans les sols. Du fait que les rsultats des tudes concernant les sols ne sont pas directement applicables au milieu souterrain, le propos de cet article est d'illustrer par des exemples la biotransformation des pesticides dans les nappes. Bien qu'il faille la considrer avec prcaution, la base de donnes sur les pesticides dans les eaux souterraines de l'Agence amricaine pour la protection de l'environnement a t utilise pour centrer la discussion sur le potentiel de biotransformation du dibromothane (EDB), de l'atrazine, des dsherbants actanilds et de l'aldicarb, qui tous ont t dtects dans les nappes des tats-Unis. Les rsultats de plus de deux douzaines d'tudes indiquent qu'il existe un potentiel de biotransformation de ces pesticides dans les nappes, bien qu'entre chacun de ces pesticides il existe des diffrences trs nettes dans la biotransformation. Ces variations sont en fait dues la fois des diffrences dans les mthodes exprimentales et dans les htrognits dans les matriaux tudis. Cependant, parce que les mcanismes de la biotransformation ne sont pas bien tudis, il est en gnral impossible d'extrapoler les prdictions du potentiel de biotransformation des sites d'tude spcifiques. Ces rsultats soulignent la ncessit de mieux comprendre la rgulation gntique microbienne des processus de biotransformation, pour que l'information gntique puisse tre efficacement prise en compte dans les futures recherches sur le potentiel de biotransformation dans le sous-sol. Resumen Se han llevado a cabo un gran nmero de estudios para evaluar la contaminacin por pesticidas en los acuferos de los Estados Unidos de Amrica.

Hydrogeology in North America: past and future  

NASA Astrophysics Data System (ADS)

This paper is a retrospective on the evolution of hydrogeology in North America over the past two centuries, and a brief speculation of its future. The history of hydrogeology is marked by developments in many different fields such as groundwater hydrology, soil mechanics, soil science, economic geology, petroleum engineering, structural geology, geochemistry, geophysics, marine geology, and more recently, ecology. The field has been enriched by the contributions of distinguished researchers from all these fields. At present, hydrogeology is in transition from a state of discovering new resources and exploiting them efficiently for maximum benefit, to one of judicious management of finite, interconnected resources that are vital for the sustenance of humans and other living things. The future of hydrogeology is likely to be dictated by the subtle balance with which the hydrological, erosional, and nutritional cycles function, and the decision of a technological society to either adapt to the constraints imposed by the balance, or to continue to exploit hydrogeological systems for maximum benefit. Although there is now a trend towards ecological and environmental awareness, human attitudes could change should large parts of the populated world be subjected to the stresses of droughts that last for many decades. Cet article est une rtrospective de l'volution de l'hydrogologie en Amrique du Nord sur les deux derniers sicles, et une brve valuation de son futur. L'histoire de l'hydrogologie est marque par le dveloppement de plusieurs techniques de terrain telles, l'hydrologie des eaux souterraines, la mcanique des sols, les sciences du sol, la gologie conomique, l' ingnierie ptrolire, la gologie structurale, la gochimie, la gophysique, la gologie marine et plus rcemment l'cologie. La science a t enrichie par la contribution de plusieurs chercheurs distingus, provenant de toutes ces branches. A prsent, l'hydrogologie est la transition entre la volont de dcouvrir de nouvelles ressources et l' exploitation la plus bnfique au possible, et un management judicieux des ressources finies, interconnectes, qui sont vitales pour l' approvisionnement des hommes et autres formes de vie. Le futur de l' hydrogologie sera dict par la balance subtile dans laquelle intervient les cycles de l'hydrologie, de l'rosion, de la nutrition, et la dcision d'une socit technologique qui s'adapterait aux contraintes de la balance, ou qui continuerait d'exploiter les systmes hydrologiques pour un bnfice maximum. Par ailleurs il y a une nette tendance inclure les aspects cologiques, les aspects environnementaux, et les changements humains qui pourraient tre influencs par les modifications hydrogologiques observes depuis une dizaine d'annes. Este articulo es una retrospectiva sobre la evolucin de la hidrogeologa en Norte Amrica en los pasados dos siglos, y una breve especulacin de su futuro. La historia de la hidrogeologa est marcada por desarrollos en muchos campos diferentes tal como hidrologa de aguas subterrneas, mecnica de suelos, ciencia del suelo, geologa econmica, ingeniera del petrleo, geologa estructural, geoqumica, geofsica, geologa marina, y ms recientemente, ecologa. El campo se ha enriquecido por las contribuciones de investigadores distinguidos en todos esos campos. Actualmente, la hidrogeologa se encuentra en transicin de un estado de descubrir nuevos recursos y explotarlos eficientemente para un beneficio mximo, a un estado de gestin juiciosa de recursos finitos, interconectados, que son vitales para el sustento de humanos y otras cosas vivientes. El futuro de la hidrogeologa posiblemente est determinado por el balance sutil con el cual funcionan los ciclos nutricionales, erosionales e hidrolgicos, y la decisin de una sociedad tecnolgica para ya sea adaptarse a las restricciones impuestas por el balance o para continuar con la explotacin de los sistemas hidrogeolgicos para un benefici

Spanish Network on Effects of Wildfires on Soils. The view after 5 years of networking  

NASA Astrophysics Data System (ADS)

1. WHAT IS FUEGORED? The Spanish Thematic Network "Effects of Wildfires on Soils" (FUEGORED, http://grupo.us.es/fuegored) has been working for over 5 years at becoming a point of reference for the study of fire-affected soils and restoration strategies. FUEGORED started in 2007, originally scheduled to run three years, as a result of the interest of Spanish researchers for developing better strategies and scientific interchange of ideas, people and collaboration between research groups. The first steps towards the establishment of a working group were a series of fieldtrips through Spain (2003), USA (2004) and Portugal (2005), where discussions about problems and research strategies arised. In its early years the network was supported by the former Ministry of Science and Innovation. This is a project to review scientific knowledge developed to date and discuss and propose future developments in scientific research about the effects of wildfires on soils. The objectives of the network are to promote and disseminate scientific research findings, provide technical and management information, and facilitate transference of knowledge between scientists, forest managers, students and society. 2. WHO IS IN THE NETWORK? The research group consists of the leading names of Spanish science in the topic and young talents, which are currently developing the most innovative research lines. Currently, the network is formed by 245 members, researchers from over 30 Spanish universities and research centers to provide the experience of decades of scientific and technical work in areas affected by forest fires and outstanding foreign researchers from Europe, Australia and America, including countries such as Australia, Italy, Lithuania, Portugal, UK, USA and others. Forest managers and technicians from various institutions are also present. 3.

To the soil genesis in tundra-forest ecotone belt in the Northeastern European Russia  

NASA Astrophysics Data System (ADS)

Ecotone belt representing the gradual transition between different bioclimatic zones (taiga and tundra) is of specific research interest. This transition zone is characterized by variety of landscapes and soil cover affected by climate changes which were accompanied with shifts of natural zones during Holocene. Paleoclimate changes had complicated the specifity of pedogenesis in the ecotone. The aim of the study was to reveal soil geneses in forest-tundra ecotone zone. The study area is characterized by drained topography and soil forming deposits represented by silty loams covering watersheds, permafrost is massive island and up to 50 m thick, permafrost table located at depths of 0,5-8 m. Vegetation cover is birch-spruce light forests where lichen-moss ground cover dominates, tree height is up to 4-6 m. Fe-illuvial svetlozoms (according to Russian classification 2004) were chosen as the study objects. According to WRB (2007) these soils are classified as Cambisols. In this soil study the complex approach was used, it includes (i) analysis of both structural organization and differentiation of functioning products on undisturbed monolith structure using mezo-micromorthologic methods; (ii) reveal of main soil-forming processes based on physical-chemical soil analysis. Quantitative chemical analysis has been conducted at an accredited laboratory "Ecoanalit" affiliated at Institute of Biology Komi SC UB RAS (Syktyvkar). Studied Cambisols are developed in upland forest sites located in the forest-tundra subzone. These soils are recognized by combination of podzolic, Fe-illuvial and cryomethamorphic horizons in the soil profile. Using of present-day methods and approaches for soil profile studies allowed to reveal the polygenesis of Cambisols which structure represents two pedogenic stages. The basis to determine these stages are the morphological features (structural organization, differentiation of cutan complex) as well as recent and inherited features of pedogenic and cryogenic processes. Upper soil has signs of present-day "cryogenic" evolution phase: features of migration of Al-Fe-humus complexes down profile. Middle and lower part of soil profile have features of taiga soil formation occurred during the Middle Holocene. Taiga stage of soil formation could be diagnosed by the presence of fragments of clay cutans and humic pedorelics. Destruction of cutan complex is a result of sharp climatic cooling occurred in Subboreal period when cryomethamorphic horizon was formed. The similar type of profile structure could be explained by specifity of soil evolution in the transition zone impacted by repeated tree line shifts during Holocene. The study was supported by Program of UD RAS, project #12--4-1004 Soil genesis in Cryolithozone of the European North-East on Abrupt Climate & Human-induced impact.

Kinetics of methane oxidation in selected mineral soils  

NASA Astrophysics Data System (ADS)

The kinetic parameters of methane oxidation in three mineral soils were measured under laboratory conditions. Incubationswere preceded by a 24-day preincubationwith 10%vol. of methane. All soils showed potential to the consumption of added methane. None of the soils, however, consumed atmospheric CH4. Methane oxidation followed the Michaelis-Menten kinetics, with relatively low values of parameters for Eutric Cambisol, while high values for Haplic Podzol, and especially for Mollic Gleysol which showed the highest methanotrophic activity and much lower affinity to methane. The high values of parameters for methane oxidation are typical for organic soils and mineral soils from landfill cover. The possibility of the involvement of nitrifying microorganisms, which inhabit the ammonia-fertilized agricultural soils should be verified.

Anthropogenic transformation of soils in the Pokrovskoe-Streshnevo Park (Moscow) and adjacent residential areas  

NASA Astrophysics Data System (ADS)

The diversity of soils within the specially protected natural territory of Pokrovskoe-Streshnevo in Moscow is discussed. The soils of this large park are not affected by the modern construction activities that delete the features inherited from the early stages of the anthropogenic transformation of soils in Moscow. They are characterized by the book-like type of soil memory, which makes it possible to trace several sequences of the anthropogenic soil transformation. The background natural soils-rzhavozems (Chromic Cambisols)have been transformed into agrogenic soils (agrosols) and postagrogenic soils (postagrosols) under abandoned plowlands, into urbo-soils and urbanozems in the areas of former or modern settlements, and into techno-soils in the areas of active excavation works and engineering reclamation. The change in the character of the land use without the accumulation of osediments on the surface leads to the development of polygenetic soil horizons.

Temporal variability of selected chemical and physical properties of topsoil of three soil types  

NASA Astrophysics Data System (ADS)

Temporal variability of soil properties measured in surface horizons of three soil types (Haplic Cambisol, Greyic Phaeozem, Haplic Luvisol) was studied in years 2007, 2008, 2009 and 2010. Undisturbed soil samples were taken every month to evaluate the actual field soil-water content, bulk density, porosity and hydraulic properties. The grab soil samples were taken every month to evaluate aggregate stability using the WSA (water stable aggregates) index, pHH2O and pHKCl, soil organic matter content and quality. Unsaturated hydraulic conductivity for pressure head of -2 cm was measured directly in the field using the minidisk tension infiltrometer. In addition soil structure was documented on micromorphological images. In some cases, the similar trends of the pHH2O , pHKCl , A400/A600, rod, P, ?field or WSA values were observed in different soils. Interestingly, the similar trends were found mostly for the Haplic Cambisol and the Greyic Phaeozem despite the fact that these soils considerably differed (different soil substrate, pedogenetic processes, etc.) and that variable crops (winter wheat and spring wheat) were planted at both locations during two years (2007 and 2006). Mostly different trends were observed for the Haplic Luvisol and the Greyic Phaeozem (soil of the same substrate). The reason could be attributed to a high vulnerability of the Haplic Luvisol to soil degradation in comparison to that of the Greyic Phaeozem. Parameters of hydraulic properties were highly variable and did not show similar trends for different soils (except the saturated soil water content and the slope of the retention curve at the inflection point for Haplic Cambisol and Greyic Phaeozem). Soil structure, aggregate stability and soil hydraulic properties were interrelated and depended on plant growth, rainfall compaction and tillage. The drier conditions in some soils positively influenced the soil aggregate stability, the slope of the retention curve at the inflection point and hydraulic conductivity. Probably due to the high variation of soil hydraulic properties no closer correlation between them and other properties was detected. Despite that the slope of the retention curve at the inflection point (which should indicate physical quality of the soil, e.g. soil aggregation and consequently soil porosity system) in many cases increased (decreased) when also the soil aggregate stability and hydraulic conductivity values increased (decreased), no closer correlation was revealed when analyzing for the entire 4 year period. The study showed different trends during different years. This was anticipated in the Greyic Phaeozem where different cops (spring wheat, winter wheat and winter barley) were planted during different years. Different trends were however observed also in the Haplic Cambisol and the Haplic Luvisol, where the same or similar crops (in both cases mostly winter wheat and ones winter barley) was sown. Results showed that climatic conditions (mostly during he winter end spring) played dominant role. Thus data, which were obtained during one year period, could not be used to generalize a soil regime in a particular soil and crop. Our results showed that it is impossible to apply any model, which would be based on statistical analyses, to predict soil properties development during one year or even longer period. Results indicate that findings cannot be used to generalize soil properties for other soil types, plants or climates.

Organic carbon distribution, speciation, and elementalcorrelations within soil microaggregates: applications of STXM and NEXAFSspectroscopy  

SciTech Connect

Soils contain the largest inventory of organic carbon on the Earth's surface. Therefore, it is important to understand how soil organic carbon (SOC) is distributed in soils. This study directly measured SOC distributions within soil microaggregates and its associations with major soil elements from three soil groups (Phaeozem, Cambisol, and Ultisol), using scanning transmission X-ray microscopy (STXM) and near-edge X-ray absorption fine structure (NEXAFS) spectroscopy at a spatial resolution of 30 nm. Unlike previous studies, small intact soil microaggregates were examined directly in order to avoid preparatory procedures that might alter C speciation. We found that SOC exists as distinct particles (tens to hundreds of nm) and as ubiquitous thin coatings on clay minerals and iron-oxides coatings. The distinct SOC particles have higher fractions of aromatic C than the coatings. NEXAFS spectra of the C coatings within individual microaggregates were relatively similar. In the Phaeozem soil, the pervasive spectral features were those of phenolic and carboxylic C, while in the Cambisol soil the most common spectral feature was the carboxyl peak. The Ultisol soil displayed a diffuse distribution of aromatic, phenolic, and carboxylic C peaks over all surfaces. In general, a wide range of C functional groups coexist within individual microaggregates. In this work we were able to, for the first time, directly quantify the major mineral elemental (Si, Al, Ca, Fe, K, Ti) compositions simultaneously with C distribution and speciation at the nm to {mu}m scale. These direct microscale measurements will help improve understanding on SOC-mineral associations in soil environments.

Impact of varying soil structure on transport processes in different diagnostic horizons of three soil types  

NASA Astrophysics Data System (ADS)

When soil structure varies in different soil types and the horizons of these soil types, it has a significant impact on water flow and contaminant transport in soils. This paper focuses on the effect of soil structure variations on the transport of pesticides in the soil above the water table. Transport of a pesticide (chlorotoluron) initially applied on soil columns taken from various horizons of three different soil types (Haplic Luvisol, Greyic Phaeozem and Haplic Cambisol) was studied using two scenarios of ponding infiltration. The highest infiltration rate and pesticide mobility were observed for the Bt 1 horizon of Haplic Luvisol that exhibited a well-developed prismatic structure. The lowest infiltration rate was measured for the Bw horizon of Haplic Cambisol, which had a poorly developed soil structure and a low fraction of large capillary pores and gravitational pores. Water infiltration rates were reduced during the experiments by a soil structure breakdown, swelling of clay and/or air entrapped in soil samples. The largest soil structure breakdown and infiltration decrease was observed for the Ap horizon of Haplic Luvisol due to the low aggregate stability of the initially well-aggregated soil. Single-porosity and dual-permeability (with matrix and macropore domains) flow models in HYDRUS-1D were used to estimate soil hydraulic parameters via numerical inversion using data from the first infiltration experiment. A fraction of the macropore domain in the dual-permeability model was estimated using the micro-morphological images. Final soil hydraulic parameters determined using the single-porosity and dual-permeability models were subsequently used to optimize solute transport parameters. To improve numerical inversion results, the two-site sorption model was also applied. Although structural changes observed during the experiment affected water flow and solute transport, the dual-permeability model together with the two-site sorption model proved to be able to approximate experimental data.

Visualization and quantification of the entrapped air bubbles by neutron imaging  

NASA Astrophysics Data System (ADS)

Preferential flow in structured soils may be accompanied by a significant temporal variation of quasi saturated hydraulic conductivity. These effects, observed in number of experiments mainly on heterogeneous soil of Cambisol series, are sometimes attributed to a changing distribution of the entrapped air within the sample. We have reproduced the variation of the quasi steady state flow during the constant head ponded infiltration experiment on the packed sample composed of three different grades of quartz sand, and visualized the water distribution during i) the initial stages of infiltration by neutron radiography and ii) during the steady state flow by neutron tomography. Provided that the hydraulic gradient is known, in the case of the experiment with ponding at the top and the seepage face at the bottom of the sample, the effective quasi-saturated (or satiated) hydraulic conductivity (KQS) is known. Gradual decrease of the KQS has been observed during first four hours of the infiltration event. Series of neutron tomography images taken during the quasi-steady state stage have detected trapping of the air bubbles in coarser sand. Furthermore, the volume of a number of entrapped air bubbles increased during the infiltration event. The fraction of the entrapped air was calculated for a series of tomography images taken during each experiment. Similarly to previous experiments performed on natural Cambisols, experimental results support the hypothesis that the effect of the gradual KQS decrease is caused by the entrapped air redistribution and the build-up of bubbles in preferential pathways. The trapped air thus restricts the preferential flow pathways and causes a lower hydraulic conductivity.

Trace element concentrations in leachates and mustard plant tissue (Sinapis alba L.) after biochar application to temperate soils.  

PubMed

Biochar application to agricultural soils has been increasingly promoted worldwide. However, this may be accompanied by unexpected side effects in terms of trace element (TE) behavior. We used a greenhouse pot experiment to study the influence of woodchip-derived biochar (wcBC) on leaching and plant concentration of various TEs (Al, Cd, Cu, Pb, Mn, As, B, Mo, Se). Three different agricultural soils from Austria (Planosol, Cambisol, Chernozem) were treated with wcBC at application rates of 1 and 3% (w/w) and subsequently planted with mustard (Sinapis alba L.). Soil samples were taken 0 and 7 months after the start of the pot experiment, and leachate water was collected twice (days 0 and 54). The extractability (with NH4NO3) of cationic TEs was decreased in the (acidic) Planosol and Cambisol after wcBC application, whereas in the (neutral) Chernozem it hardly changed. In contrast, anionic TEs were mobilized in all three soils, which resulted in higher anion concentrations in the leachates. The application of wcBC had no effect on Al and Pb in the mustard plants, but increased their B and Mo concentrations and decreased their Cd, Cu and Mn concentrations. A two-way analysis of variance showed significant interactions between wcBC application rate and soil type for most TEs, which indicates that different soil types may react differently upon wcBC application. Correlation and partial correlation analyses revealed that TE behavior was primarily related to soil pH, whereas the involvement of other factors such as electrical conductivity (EC), organic carbon (OC) content and dissolved organic carbon (DOC) was found to be more soil and TE-specific. The application of wcBC may be a useful strategy for the remediation of soils with elevated levels of cationic TEs, but could lead to deficiencies of cationic micronutrients and enhance short-term translocation of anionic TEs towards the groundwater at high leaching rates.

Influence of polluted air on chemical composition of elements from forest ecosystems from the region of Srednogorie (Bulgaria)  

NASA Astrophysics Data System (ADS)

Studied region is situated on the south steep slopes of Central Balkan Mountains with south-west and south-east aspects. In the lower parts sediments parent materials are presented sandstones, shales, limestones and conglomerates. Over 800 m the southern Bulgarian granites, gneiss and crystalline shale are distributed and the formed soils could be referred as Eutric-Dystric Cambisols. In the middle forest zone of the area the pure and mixed beech forest (Fagus sylvatica L.) are distributed. The most distributed soil types in studied region are Dystric Cambisols. Soil acidity slightly varies pH is between 4.7 and 5.0 while more acid are the superficial 0-5 cm of soils. The mean values of organic carbon content are higher for the upper soil layer (61.7 g/kg). The heavy metals contents (Cu, Pb and Zn) in the superficial layers are little higher compared with the determined limit values for soils. The content of Zn increased toward deeper layers of soil profile, while the content of Cu decreased slowly. For the Pb small variation in the profile distribution are observed. Concerning the heavy metals content in forest floor layers higher values are determined for Cu and Pb in Aof and Aoh, 540 mg/kg and 903 mg/kg for Cu and 100 mg/kg and 168 mg/kg for Pb respectively. These high values of Cu are indicator for anthropogenic influence in the region, provoked by the activities of copper production enterprise CPE Georgi Damyanov in town of Srednogorie. The high values for heavy metals content in forest floor, the significant soil organic matter content and lower pH values supposed a higher anthropogenic impact on brown forest soils in studied region.

Disturbances can control fine-scale pedodiversity in old-growth forests: is the soil evolution theory disturbed as well?  

NASA Astrophysics Data System (ADS)

Biota-soil interactions in natural ecosystems are the subject of considerable research. Our hypothesis is that individual trees play a significant role through biomechanical and biochemical disturbances affecting soil formation in temperate forests, resulting in a complex spatial pattern of disturbance regimes and a close relationship between disturbance histories and soil units. In ofnsk Prales (Czech Republic) - the fourth oldest, continuously protected reserve in Europe and the first site of global research network SIGEO (Smithsonian Institution Global Earth Observatories) in continental Europe - we compared extensive dendrochronological, soil and pit-mound microtopography data both temporally and spatially from an area of anthropogenically unaffected 42 ha collected from 2008-2012. These data sets differ in terms of information complexity and length of memory: tree cores contain complex information about the disturbance history of the past 350 years, footprints of disturbances from the uprooting of a specific tree can persist 1700 years, and soils represent an extensive composite phenotype that has been developing for at least the entire postglacial period (10 500 years). On average, 6.18-13.41% of the canopy on individual soil units was disturbed per decade. Even though the "backbone" of key events in the development of the forest ecosystem remained the same (e.g. the 1870s, 1880s and 1980s), the internal structure of disturbance history often differed among soil units; the most exceptional were Gleysols and Histosols, where important feedback from soil to trees was expected. However, the characteristics of treethrow dynamics as well as the frequencies of stronger releases in core series also significantly differed along a gradient of terrestrial soil weathering and leaching (Haplic Cambisols - Dystric Cambisols - Entic Podzols - Albic Podzols). These results suggest the existence of several disturbance regimes within the forest, controlling fine-scale pedodiversity.

Evaluating the importance of surface soil contributions to reservoir sediment in alpine environments: a combined modelling and fingerprinting approach in the Posets-Maladeta Natural Park  

NASA Astrophysics Data System (ADS)

Soil in alpine environments plays a key role in the development of ecosystem services and in order to maintain and preserve this important resource, information is required on processes that lead to soil erosion. Similar to other mountain alpine environments, the Benasque catchment is characterised by temperatures below freezing that can last from November to April, intense rainfall events, typically in spring and autumn, and rugged topography which makes assessment of erosion challenging. Indirect approaches to soil erosion assessment, such as combined model approaches, offer an opportunity to evaluate soil erosion in such areas. In this study (i) the SWAT (Soil and Water Assessment Tool) hydrological and erosion model and (ii) sediment fingerprinting procedures were used in parallel to assess the viability of a combined modelling and tracing approach to evaluate soil erosion processes in the area of the Posets-Maladeta Natural Park (central Spanish Pyrenees). Soil erosion rates and sediment contribution of potential sediment sources defined by soil type (Kastanozems/Phaeozems; Fluvisols and Cambisols) were assessed. The SWAT model suggested that, with the highest specific sediment yields, Cambisols are the main source of sediment in the Benasque catchment and Phaeozems and Fluvisols were identified as the lowest sediment contributors. Spring and winter model runs gave the highest and lowest specific sediment yield, respectively. In contrast, sediment fingerprinting analysis identified Fluvisols, which dominate the riparian zone, as the main sediment source at the time of sampling. This indicates the importance of connectivity as well as potential differences in the source dynamic of material in storage versus that transported efficiently from the system at times of high flow. The combined approach enabled us to better understand soil erosion processes in the Benasque alpine catchment, wherein SWAT identified areas of potential high sediment yield in large flood events but sediment fingerprinting identified areas that, due to high connectivity, contribute more to channel-stored sediment deposits.
