The quality of irrigation by sprinklers is determined not only by the uniformity of the distribution of the rain layer over the irrigated area. If the water permeability exceeds the intensity of precipitation, then surface runoff does not occur. With an increase in soil moisture, water permeability decreases, and surface runoff increases, contributing to the washout of the fertile layer. The sprinkling machine “Kuban-LS” is installed 18…20 km west of Volgograd, located on the western slope of the Volga Upland. The soil cover has a complex character and is represented by carbonate light chestnut varieties of varying degrees of washout. The data on the effect of artificial rain created by a sprinkler machine on the soil structure and absorption rate are presented. Due to the partial destruction of agronomically valuable soil aggregates, the density of the arable layer from sowing to harvesting the grass mixture after each irrigation increased from 1.10…1.28 to 1.26…1.35 t/m 3 . The quality of irrigation by sprinklers is determined not only by the uniformity of rain distribution, but also by the conditions for the absorption of irrigation water into the soil. Based on these studies, we offer certain recommendations to reduce the negative impact on the soil.
