Abstract
Abstract Soybeans (Glycine max L. cv. PI 54619–5–1) were grown for 28 days in a glasshouse in calcareous Hacienda loam soil in pots to which had been banded in the center of 500 g pots the following iron amendments: control, 25 g of a commercial sulfur‐iron (8%) mixture*, 25 g sulfur, 20 g sulfur + 5 g iron sulfate, 25 g of a commercial iron oxide mixture**, 25 g iron pyrite***, 12.5 g each of iron pyrite and sulfur, 25 g iron sulfate, and 12.5 g each of iron oxide and sulfur. Most rapid and complete greening was with iron sulfate or iron oxide alone or in combinations. Sulfur and pyrite‐treated plants did not become green until about the 3rd week. Banding of all amendments increased Fe concentrations of leaves. Banding of sulfur did not result in increased Mn in leaves but pyrite resulted in some Mn toxicity and in increased Zn, Cu, Al, Ni and Pb in leaves with decreased leaf growth.
