Abstract
The purpose of the research is to analyze the parameters of changes in the agro-climatic conditions of the Central Non-Chernozem region and to assess the possibility of introducing soybeans into new cultivation regions. The introduction of soybean crops into new cultivation regions is an urgent task to solve the problem of providing the processing industry with relatively cheap and high-grade protein. The trends of changes in climatic conditions in the regions of the Central Non-Chernozem region for the period from 1981‑2020 are analyzed. The expansion of soybean sowing areas in the Central region of the Non-Chernozem zone is hindered by stressful conditions that form during the period of filling and ripening of seeds, first of all – limited thermal resources. As a result of the analysis of agro-climatic data, the trend of local climate warming in all regions included in the Central Region of the Non-Chernozem zone of Russia has been revealed. The values of the sum of active temperatures in different agro-climatic subzones increased by 200‑250°C, the amount of precipitation falling during the growing season decreased by 20‑40 mm, the hydrothermal coefficient of G.T. Selyaninov (GTC) decreased by 0.3‑0.4 points. The changes led to a shift of the isotherm of the sum of active temperatures by 150‑200 km towards high latitudes. In 1981, the isotherm passed through the northern part of the Bryansk and Orel regions, included a small fragment of the Kaluga region and the Ryazan region, but at the moment it is located on the northern border of the Moscow region, affecting the territory of the Tver and Vladimir regions, as well as the southern part of the Kostroma region.
