In particular, among the methods of economic-mathematical modeling, it is appropriate for this task to use the following: linear programming, system-dynamic and simulation modeling, graph theory approaches. The criteria of optimality and limitations of the arrangement of agricultural land and the formation of crop rotation arrays are substantiated, including: the maximum possible return of organic substances to the soil, the maximization of energy efficiency, the maximization of indicators of marginal income by types of agricultural crops at the minimum production cost of their cultivation, taking into account individual items of direct costs for fertilizers and other production resources, soil quality scores according to their suitability for growing certain crops, restrictions on their rotation, the influence of predecessor crops, other restrictions, for example, regarding farm specialization. Methodical approaches to the economic-mathematical model of crop rotation have been developed, which include linear programming, where the multi-criteria indicator of energy and economic efficiency is assigned to the maximum function, the sown areas of individual agricultural crops in a certain harvest year to the variables, and the remaining parameters are defined as environmental, production, technological and resource limitations. An analysis of the optimality of the arrangement of agricultural land and the formation of crop rotation arrays by simulation modeling methods is proposed. It is important to use data from long-term stationary experiments to study the rotation of agricultural crops in crop rotations that last more than five rotations. Reporting on actual fields and crop crops is proposed, which should be spatially defined (with crop boundaries on the map). Product Description popup.authors Avramchuk Bohdan O. Barvinskyi Andrii V.
