Status of soil microorganisms st simulaneous application of mineral fertilizers and the products of aerobic biofermentation

摘要

The products of aerobic biofermentation were applied for soil under potato and pea-oat mixture on background of mineral fertilizers in the field experiments. Quantity of different soil microorganisms species and mineralization indexe of soil and fertilizers were estimated. It was shown that application of low dose of biofermentation products is the most expedient. Increased doses of biofertilizers give rise to high concentration of denitrificating microorganisms and.
