Abstract

The article presents the results of research on the effect of sprinkling on the structural and aggregate composition of soil and its density. The high quality of sprinkling irrigation is achieved with uniform distribution of rain over the area, acceptable intensity with drop diameter and impact force, at which plants and soil structure are not damaged, puddles and surface runoff are not formed. For complete absorption of water into the soil and preservation of soil structure the rain of low intensity, with small drops is required. When applying sprinkling it is necessary to take into account the granulometric composition of the soil, slope, classification of the cultivated crop to coordinate it with the permissible intensity of rain. Erosion control measures should be applied only in a complex, as some of them cannot be replaced by any other. The system of erosion control measures should be properly combined and adapted to the forms of the land surface and local soil and climatic conditions and to develop measures to minimize the negative impact of irrigation on the soil.
