Imbalance of nutritional substances of the soil at the modern stage of development of agricultural production in Russia

Abstract

The paper is devoted to the analysis of changes in the gross harvest of crops from 2008 to 2017. Nutrient removal volumes according to their types with the yield of main commercial crops, including 1 hectare of each crop area are calculated. Volumes of removal by type of nutrients are established. The removal of nutrients with the yield and the application of mineral and organic fertilizers when growing major crops are compared. The size of the nutrient removal over their application in general, including the main crops and types of nutrients is estimated. Proposals to improve the effective soil fertility by increasing the use of fertilizers are formulated. The authors consider ways of these proposals implementation.
