ECONOMIC AND MATHEMATICAL MODELING IN THE SYSTEM OF PRECISION AGRICULTURE

The article suggests an economic and mathematical tool for optimization of production costs as a tool for justifying the efficiency of resource-saving production methods in the precision farming system. In particular, an economic and mathematical model of optimization of resource saving in agricultural production has been developed, which provides the most objective, in comparison with known analogues, justification of certain resource-saving technologies for the agricultural production due to integrated consideration of natural and production factors, including the difference in the amount of production resources at areas with various agrochemical characteristics; these characteristics were identified on the basis of soil tests, crop losses, depending on a technology of crop cultivation, a degree of reproduction of soil fertility, a product quality and the environmental safety of production. The practical implementation of precision farming technologies is based on capabilities of modern geo-information systems GLONASS. Thus, the conducted studies suggest that economic and mathematical modeling, as one of the elements of the economic mechanism of resource saving, can be successfully used to optimize resource consumption in agricultural production. The approbation of the improved economic and mathematical model has proved a possibility of more accurate and objective justification of the use of one or another resource-saving method (technology) of production.
