Agroeconomic and environmental assessment of crop rotation

Abstract

This work considers the problem of comparative assessment of crop rotations from the point of view of agroeconomic efficiency and environmental feasibility. It has been suggested that such an evaluation should be carried out in two stages. At the first stage, individual crops are assessed according to their productivity in grain units and the cost of production (agroeconomic indicators) and according to the balance of humus and basic nutrients (ecological indicators). At the second stage, each crop rotation with its own structure of crops is evaluated according to the specified criteria. Three options, or levels of fertilization, are subject to evaluation: without fertilizers, with the application of the first quintal of active substance, and with the application of environmentally justified fertilizer norms.
