Interactions between zinc and manganese EDTA applied to corn plants at mdderately high levels

Abstract

Corn (Zea mays L.) plants were grown in Hacienda loam soil with different levels of zinc and manganese EDTA applied singly and in combination. The highest levels of both together resulted in additive and synergistic effects. Caution, therefore, should be exercised when both zinc and manganese EDTA are supplied to crops simultaneously to correct deficiencies.
