aref2 2 It has been studied the effect of new complex fertilizer "Suprodit" and industrial fertilizers (NPK and "nitrophoska") on the biological activity of soddy-podzolic soil, contaminated with Cd, Zn, Cu at different doses (6, 600, 390 mg/kg accordingly). The using of "Suprodit" increased the CO2 emission rate on Cd, Zn, Cu contaminated soil by 1,5-3,3 times in comparison with NPK and "nitrophoska". "Suprodit" stimulated the enzymatic activity of soil dehydrogenase 1,2-2,0 times, and soil invertase 1,1-1,5 times on Cd, Zn and Cu contaminated soil in comparison with two another fertilizers, accordingly. It has been shown that Suprodit is the most effective fertilizer comparison with industrial fertilizers to reduce negative effects of heavy metals on the soil fertility on contaminated lands.
