Excess EDDHA (ethylenediamine di(o-hydroxyphenylacetic acid) had little effect on leaf concentrations of Fe in bush beans (Phaseolus vulgaris L. var Improved Tendergreen) when grown in nutrient solution at three pH values from 4.3 to 8.7. An excess of EDDHA 20 times that of Fe decreased yields slightly, but not as result of Fe deficiency. A resulting hypothesis is that chelated Fe can be transferred from chelating agent to uptake sites on roots without going in the ionic form through the solution around roots.
