Melnyk P. Ecological and economic bases of management of nature management in agroecosystems

In the thesis the essence of environmental and economic management of nature management in agroecosystems is investigated. The scientific and methodological foundations of environmental and economic management in the nature management of the agroecosystem are generalized. Zonal features of the phases of the solar activity cycle in the production of winter wheat are established. The phases of the cycle of sonic activity and their deterministic coefficients in the zonal analysis of agroecosystems are determined. The probability of linking the production of wheat by winter to the Earth's magnetic field is proved. The coefficients of determination between the phases of the solar activity cycle and the winter wheat yield are determined. A model of management of nature management in agroecosystems is developed taking into account the geomagnetic field and solar activity.
