Abstract

Aim. To explore the peculiarities of nitrogen transformation in sod-podzolic soils with corn growing under dif- ferent fertilizer types and the effect of bacterization. Methods. Agrochemical, fi eld and lyzimetric, chromato- graphic determination of nitrogen fi xation activity and emission of N 2 O. Results. The highest losses of nitrogen from the soil occurred in the variants with manure application and use of mineral fertilizers N 90 P 90 K 90 . The processes of nitrogen transformation in soil and corn yield were optimized using the combination of mineral fertilizers with green manure and microbial agent. Conclusions. The application of fertilizers for corn grow- ing on sod-podzolic soils of Polissya region should be accompanied with the use of green manures. The use of microbial preparations is recommended.
