Abstract
Experiments were performed concerning the influence of soil organic matter on Cd availability to wheat seedlings.
Cadmium added to soil was bound by alkali soluble humic substances through linkages so strong that it was not removable by seedlings under toxic limit. Cadmium linked by organic matter was principally found in fulvic acids, and after polyamide chromatography of the latter, all fulvic Cd was completely recovered in first fraction which contained the major part of aminoacid compounds.
These findings suggest that interactions between Cd and proteic substances, frequently reported in studies on animal tissues, are active in soil too.
