Energy-ecological efficiency of agroecosystem of West Kazakhstan

Abstract

The negative balance of the reproduction of soil energy indicates a deep ecological and energy crisis in agriculture. Analyzed: indicators of the use of biological factors, such as solar energy and the energy of soil fertility, affect the ecological and economic efficiency of agricultural production; the efficiency of using solar energy and the coefficient of its efficiency. The required level of productivity has been determined to maintain the annual deficit-free soil balance in the western region of Kazakhstan. The necessity of state regulation to determine the critical threshold of the yield level to compensate for the deficiency of soil energy at the expense of other sources of organic matter has been substantiated. For the modernization and ecological optimization of agriculture, a bio-energetic model of individual crop rotations was built, which also includes indicators of crop yield, the degree of mineralization of soil organic matter and some other standard indicators.
