Abstract

The entire iron requirement of tomato, sunflower, corn and barley, growing in nutrient soln. can be met by a single addition of 5-10 ppm. of iron complexed with K ethylenediamine tetra-acetate. For best results, the complex should be prepd. with equi-molar ratios of Fe and complexing agent. The complex is stable and relatively non-toxic.
