Mutual effects between Mn, Ca, and Mg were studied during steady-state absorption experiments with excised barley roots. Calcium appeared to enhance the rate of Mn absorption; whereas, Mg had a highly depressive effect. The combination of both Ca and Mg was even more inhibitory to Mn absorption ...

Large differences in absorption behavior are caused by changing the root to solution ratio in absorption experiments. Aeration ordinarily is not a factor. Changes in pH as a result of absorption activity cause a reduction in absorption rates. This factor may be eliminated by ...
