The influence of moisture on the residual effects of natural zinc chelates applied to two different soils

The aim ofthis study was to compare the behavior ofresidual Zn from three natural chelates (Zn-aminolignosulfonate [Zn-AML],Zn-polyhydroxyphenylcarboxylate [Zn-PHP] and Zn-ethylenediamine disuccinate [Zn-EDDS]) applied at different rates (0, 5 and 10 mg Zn/kg soil) to a flax crop grown during the pr...
