Abstract
The article presents information on the distribution of hydromorphic soils, their general properties and mechanical composition of irrigated meadow, bog-meadow, graymeadow soils of the Denovsky district of the Surkhandarya region. The mechanical composition of meadow soils is closely related to such factors as the composition of irrigation materials, the thickness of the agro-irrigation layer, the duration of the irrigation period, and even the formation of soil with different mechanical composition in different parts of the meadow, a field irrigated from one ditch, recommendations are made aimed at carrying out agrotechnical and agrophysical activities on pasture soils, taking into account the mechanical composition.
