Carbon and nitrogen cycles under different fertilization systems in the rotation on sod-podzolic soil in Polissya

This paper deals with investigation results of the organic and mineral fertilizers influence on productivity of briefly rotational grain-tilled crop rotation, humus condition of sod-podzolic soil, depending both on the amount of biomass coming into the soil as well as the ratio of C:N. It has been found that the use of by-products and green manuring on the background of N50P56K69 has a positive effect on the humus soil and reduction of CO2 emissions into the atmosphere with almost the same performance of crop rotation with traditional organic-fertilizer system (10 t/ha of manure + N50P56K69).
