Abstract
Heavy metals (Cd, Zn, Cu) and agroameliorants effect on biological activity of the soddy-podzolic soil (carbon dioxide release; denitrifying process) and barley productivity. Results of the study have shown that Zn and Cu are more toxic in comparison with Cd, because decrease the rate of carbon dioxide release of the soil in 1,6 times; the rate of denitrification in 1,4 and 2,3 times, appropriately. Usage of the long-acting fertilizer SYPRODIT on the soddy-podzolic contaminated with heavy metals soil is more effective in reducing of negative influence of heavy metals on the process of organic matter destruction and soil fertility compared to variants with nitrofoska and NPK.
