Studies were made to determine if the chelating agent nitrilotriacetate (NTA) when applied to soil in large amounts could cause toxicities to plants by resulting in increased availability of heavy metals. NTA at 2500 ppm applied as the Na salt in soil of pH 6 was slightly toxic in bush beans (Phaseolus vulgaris L., var Improved Tendergreen). NTA applications at lower rates resulted in increased concentrations of Fe, Zn, Mn, Cu, Mo, Co, Ni, and Al in leaves of bush beans. Soybeans (Glycine max (L.) Merr. Bragg, var. P154619-5-1) grown in Hacienda loam soil at levels from 100 to 1000 ppm had increased concentrations of several heavy metals and also of Ca, K, and Mg in leaves, but there was no apparent yield decrease. Only slight effects could be expected from concentrations likely to be found in effluent water. 5 references, 2 tables.
