Abstract
Abstract Carrier‐free 59 Fe and 65 Zn were added to Dinuba fine sandy loam (neutral), Hacienda loam (calcareous), and Yolo loam (slightly acid), and equilibrated through drying and wetting cycles. Bush bean ( Phaseolus vulgaris L., var. ‘Improved Tendergreen’), corn ( Zea mays L., var. ‘Golden Cross Bantam’), and soybean ( Glycine max Merr., var. ‘PI‐54619‐5‐1’ and ‘Hawkeye’) were grown in 59 Fe‐containing soil and bush bean ( P. vulgaris L.), corn ( Z. mays L.) and cotton ( Gossypium hirsutum L., var. ‘Acala 442’) were grown in 65 Zn‐containing soil. One‐half of those with 59 Fe received Na 2 EDDHA equivalent to 4.4 kg of Fe/ha had there been a 1:1 metal chelate and one‐half of those with 65 Zn received Na 2 EDTA equivalent to 5.5 kg of Zn/ha had metal been added with the chelating agent. The chelating agents had many different effects depending on soil and on crop. Chelating agents increased the specific activity of 59 Fe in the bush bean and soybeans. The specific activity of 59 Fe in corn was unchanged by chelating agent but was much higher than in bush bean and soybean with or without chelating agents. When carrier Fe was added, the behavior of 59 Fe was essentially unchanged. The specific activity of 65 Zn in plants in most cases was increased by the EDTA. The EDTA increased both 65 Zn and total Zn in corn, but the specific activity generally was unchanged by the chelate.
