MORPHOLOGICAL, AGROCHEMICAL AND AGROPHYSICAL CHARACTERISTICS OF RAINFED LIGHT GRAY SOILS COMMON IN THE NURATA MOUNTAINS OF THE NAVOIY REGION

The article presents morphological features and agrochemical, agrophysical data of rainfed light-gray soils, common in the Nurata mountains of the Navoi region. The studies summarized the soil dryness of rainfed - light gray soil is 15.03-25 %. The soil-forming rocks are eluvially, diluvial and proluvial sediments: salinity, conglomerates, sandstones, and gravelly-peat sediments and loess-like loams. The main part of rainfed - light gray soils is not saline, but in some areas there are medium and strongly saline horizons. In terms of the mechanical composition of rainfed light-colored gray soils, sawn fractions predominate. These soils are low and the arable horizon is up to 22 % in composition and up to 17.34 % down the profile. Rainfed - bright gray soils are characterized by the absorption capacity, which, according to the sum absorbed by the base, is 7-8 mg / eq. Per 100 g. soils According to the agrochemical characteristics of the soil, the content of humus is very poor, the amount of humus in the arable horizon is 0.73 %. The availability of exchangeable potassium and phosphorus is very low. The high carbonate content is due to the carbonate of soil-forming rocks.
