MODERN SOIL CONDITION OF ZAAMIN HAVOUS TRANSPORT CONES AND THEIR MAIN PROPERTIES
The article summarizes the results of many years of research, the Zaamin of the Havast cone on the study of the main properties of gray-meadow meadow solonchak, low humus soils. The hungry steppe, spread over a vast piedmont plain, from the south adjoining the foothills of the Turkestan Range. The territory of the distribution of gray earth meadow soils is located in the Turan soil and climatic province, in the belt of light gray earth. Over time, due to changes in hydrogeological conditions, most of them were transformed into gray-meadow and meadow soils, often prone to secondary salinization. Some of these soils are gypsum-bearing. The described soil is almost completely used in irrigated agriculture. The mechanical composition of the soil is mainly medium and heavy loamy, sometimes with layers of light particle size distribution. These soils are formed with a depth of groundwater of 2-3 m. They are considered transitional from serozem to meadow soils. According to the degree of salinization, the soils are slightly and medium saline, with spots sometimes very saline. Sulfates prevail in the composition of water-soluble salts. The type of soil salinization is chloride-sulfate and sulfate. According to the content in the gypsum profile, the described soils are divided into weakly and medium gypsum. According to the humus content, the soils are low and middle-income. Carbonates have been distributed unevenly with a maximum in the upper horizons. Calcium predominates in the absorption complex. The described soils have a high potential fertility.
