Abstract

The article presents the agrochemical and chemical properties of typical sierozem and meadow soils of the Tashkent region. According to the results obtained, typical serozem and meadow irrigated soils, in terms of the degree of humus and the supply of nutrients in the studied soils, have a low humus content (0.36-0.87%), a very low content of mobile phosphorus (5.33-15.60 mg / kg) found low (100-200 mg / kg) exchangeable potassium, in typical sierozem soils, irrigated in accordance with the chemical properties of the soil, the amount of dry residue varied within 0.125–0.145% along the soil profile, and this indicator gradually decreased from the upper layers to the lower ones. The Cl content was 0.007% in the upper layers and 0.003% in the lower layers, and no significant changes were observed in this profile. According to the analysis of water absorption in irrigated meadow soils, the amount of dry residue along the profile was 0.090-0.120%, and along the profile its amount increased downward. The amount of Cl- is practically the same along the soil profile, i.e. 0.007%.
