Еconomic-mathematical substantiation of efficiency of mineral fertilizer use in agricultural enterprises

The essence of the economic efficiency of mineral fertilizers use and methodology of its determination, the theoretical aspects of the production functions as the basis for planning and organization of an efficient use of mineral fertilizers, methods of calculation of fertilizer norms to the intended yield based on discrete and direct approach are investigated. The current status, trends and economic efficiency of mineral fertilizers use in agricultural enterprises is revealed, systematic comparative analysis of the feasibility of mineral fertilizers use based on discrete and direct functional approaches is carried out. The economic and mathematical analysis of the results of approbation of production functions for optimal use of mineral fertilizers under spring barley and winter wheat is carried out, proved the feasibility of the analog use of agro economic system «cropping system» in agricultural enterprises.
