THE INFLUENCE OF RESOURCE-SAVING TECHNOLOGIES OF SOIL TILLAGE ON WATER REGIME OF DARK-CHESTNUT SOIL

The purpose of research is to identify the role of minimum and zero technology of cultivation of goldof-pleasure on the dynamics of the water regime, density and structure of dark chestnut soil in the dry steppe zone. Scientific research was carried out in the four-field crop rotation. The scientific novelty of the research results lies in the fact that for the first time in the agro-ecological conditions of the dry steppe zone of Northern Kazakhstan the regularities of changes in the quantitative and qualitative parameters of water and agrophysical properties of dark chestnut soil when using different intensity tillage systems. It is established that in addition to increasing water infiltration, reducing evaporation costs, increasing the amount of water available to plants, minimum and zero tillage technologies have a positive impact on the physical and biological properties of the soil. At the same time, a significant excess of the yield of gold-of-pleasure on the minimum and zero tillage in comparison with multifunctional was revealed.
