Optimization models of agricultural production with heterogeneous land resources

Abstract

The paper identifies information that takes into account the heterogeneity of agricultural land on the basis of the use of a precision farming system and geographic information technologies. The tasks of optimizing the production of agricultural products are formulated, describing the heterogeneity of land resources, for averaged and extreme weather and climatic conditions. These models are implemented for an agricultural enterprise in the Irkutsk region. Two variants of the problem are considered: with deterministic and stochastic parameters. As a random variable, the problem uses the crop yield corresponding to the probability of a drought that occurred in the region in 2015. According to the calculations, the use of various technologies of precision farming, taking into account the heterogeneity of arable land, makes it possible to increase the income of the enterprise, reducing the dispersion of the coefficients included in the optimization model agricultural production. At the same time, it is possible to reduce the risks associated with extreme hydrometeorological events, in particular, with drought

The use of resource-saving technologies in crop production

“…The problem of using resource-saving technologies in domestic production is expressed by high labor costs. World experience shows that labor costs for the production of crop products in developed countries are 2-3 times less than in domestic [5][6]. The management of agricultural organizations is forced to look for ways to reduce costs through the introduction of modern energy and resource-saving technologies that ensure rational resource consumption.…”
