Cd and Zn Concentrations in Soil and Silage Maize following the Addition of P Fertilizer

Studies of soil Cd and Zn are often performed on sites that contaminated or have deficient conditions. Soil characteristics crop management could impact the mobility uptake Zn, even when considering unpolluted soils adequate levels. The concentrations these two metals were assessed in silage maize under five P fertilization treatments at growth stages low sufficient Pearson correlation coefficients stepwise linear regressions calculated to investigate influencing bioavailable metal fraction concentration maize. did not accumulation maize; however, was affected by placement leaf development stage. From early maturity, level decreased 10% initial uptake, while 50% uptake. This reduction both may be attributed a dilution effect derived from high biomass production. Silage alleviate diminishing depressant fertilizer concentration. Further research is required understand its relation field conditions mature stages.
