THE IMPACT OF AGROTECHNICAL MEASURES ON PRODUCTIVITY INDICATORS OF TYPICAL IRRIGATED GRAY-SOIL

The article presents the importance of studying the impact of agrotechnical measures on the productivity of typical irrigated gray-earth soils, changes in the properties of typical irrigated gray-earth soils under the influence of fertilizers. In addition to a sufficient amount of organic and mineral fertilizers in the soil, attention should be paid to improving the soil structure. In order for the soil to be fertile, it is necessary to study its properties, composition and various processes occurring in the soil. The aim is to study the distribution of fertility indicators of typical gray-earth soils, the influence of erosion processes on them, the influence of anthropogenic factors and agrotechnical measures-irrigation, mineral fertilizers, organic fertilizers on soil fertility. Various types of crops, mineral and organic fertilizers affect soil fertility. As a result of the conversion of organic residues, the soil is enriched with nitrogen.
