Effect of Different Moisture Regimes and Added Iron on the Availability of Zinc and Copper in Black Soils

Abstract

An incubation experiment was conducted with black soil in the laboratory to determine the effect of changes in moisture regime and added iron on the availability of zinc and copper at different intervals of incubation period. The availability of Zn and Cu were influenced both by moisture regimes and applied Fe. The results clearly indicated that available Zn and Cu were depressed by increasing level of moisture regimes. An antagonic effect was observed between available Zn and added Fe.
