Fertilizers effects on spring wheat productivity and heavy metals (Cd, Zn, Cu) accumulation in plant
Abstract
Results of a 2-year greenhouse experiment have shown, that fertilizers differently effect on spring wheat productivity and heavy metals accumulation in the plant. Contaminated with Cd, Zn и Сu soddy-podzolic soil shown 10-45% lower wheat yield, compared with the soil without heavy metals. Zn effects more negative on growth and formation of wheat yield, especially in a variant with NPK-amended soil. In the second year, the effect is the same. Suprodit-amended Cd, Cu and Zn contaminated soil showed a 1,4-2,0 lower uptake of heavy metals in the plant than NPK and nitrophosphate-amended soils in the first year and a 1,4-2,2 - in the second year.
