摘要：
The biomass and activity of denitrifying bacteria in soddy-podzolic soils treated with mineral fertilizer have been determined at several plots with different fertilizer backgrounds (organic, mineral, and organomineral). The rate of N2O emission increased two times upon applying mineral fertilizer and was at its maximum on the mineral background. The influence of different ecological factors (the biomass of denitrifying bacteria, the content of mineral nitrogen and organic substances, and the degree of soil cultivation) on the amounts of gaseous losses of nitrogen during denitrification was examined.
