EVOLUTION OF IRRIGATED SOILS "CENTRAL FERGANA" UNDER THE INFLUENCE OF ANTHROPOGENIC FACTORS

Abstract

It is known that the study of the historical development of soils is an important task in determining the direction of changes in their cross-section and thereby developing a system of integrated measures to address many issues, such as their conservation and productivity, improvement and rational use. The historical development of soils means that the already developed full-profile soils change in connection with the evolution of the whole natural environment. In this case, one genetic type or type of soil can pass to another genetic type or type. As a result, the characteristics of the previous soil formation stage in the soil profile gradually begin to fade or transform, and new characters are formed in accordance with the new stage of soil formation.
