ABSTRACT:
N-carboxymethyl-N-(hydroxybenzyl)-asparagic acids which may be further substituted in the phenyl nucleus possess metal-chelating properties for metals such as iron magnesium, calcium, manganese, cobalt, nickel, copper, zinc, cadmium or related metals. Chelates of this type may be used for the regulation of metal-deficiency phenomena in plants.
