Abstract
The parameters of soil fertility are reported for the application of fertilizers and cultivation under different soil and climatic conditions. The influence of the leading anthropogenic factors on the changes in the parameters of nitrogen conditions in soil, on the assimilation of nitrogen in plants and on the productivity of plants is demonstrated. A schematic of the main fluxes of nitrogen is presented and the ways to adjustment of nitrogen nutrition in agricultural ecosystems are outlined.
