Химическая и агрохимическая характеристика пустынно песчаных почв

The article given are results of a study of the chemical and agrochemical properties of desert-sandy soils of the Konimekh district of the Navoi region. According to the results of the research, it was revealed that desert-sandy soils are very low in humus, low and medium in mineral nitrogen and mobile phosphorus, medium and high in exchangeable potassium. Carbonates are almost unevenly distributed over the profile of sandy desert soils, if in some sections of the soil there is a high carbonate content in the upper horizons, then in other sections of the soil there is some accumulation of carbonates in the middle and lower layers. A certain regularity is observed in the distribution of gypsum along the soil profile, it occurs mainly in very small quantities, but in the lower layers of some sections of the soil, an increase in the amount of gypsum is observed depending on the genesis of the soil.
