The variability of chemical composition of winter rye harvest under the influence of the Extrasol biological preparation, mineral fertilizers and seed dressing is considered. The values of economic and normative removal of basic nutrients in conditions of gray forest soil are established. The size of the normative removal of nitrogen, phosphorus and potassium by winter rye has been relatively stable, although slightly increased from the introduction of mineral fertilizers.
