FARG‘ONA VODIYSI SUG‘ORILADIGAN YERLARIDA AGROIRRIGATSION QATLAMLARNING SHAKLLANISHI VA UNING XOSSALARI
The article presents the process of formation of agro-irrigation horizons using the example of alluvial sediments common on the alluvial fan of the Sokh River. Also noted are changes in the composition of irrigation waters, the degree of mineralization and salinity of soils, as well as the influence of mechanical composition, physicochemical and biological properties of soils. On the accumulation of sediments, attention is drawn to the fact that the Sokh River occupies a leading position among the rivers of the Southern Fergana in terms of sediment content. It is noted that on soils with alluvial-proluvial parent rocks, in the process of formation of irrigated colmatated soils, river sediments play a decisive genetic role and contribute to the formation of agroirrigation horizons of varying thickness.
