Chemical properties of irrigated grass-alluvial soils distributed in the aral areas

This article presents the results of a study on the agrochemical properties and salinity levels of irrigated grassland-alluvial soils distributed in the Aral Sea region. The results of the study show that the soils of the studied area are characterized by poor humus supply. The distribution of humus along the soil profile is based on clear laws. In the soils of the region, large amounts of humus and nutrients are distributed in the upper driving layers and a quantitative decrease is observed from the top to the bottom layers. Chlorine and sulfate anions predominate in soils. Also, weakly saline and non-saline soils are relatively high in humus and nutrients than moderately saline soils.
