“…Processes such as the emergence and development of life in dried seabed soil can be observed only by studying the microbiological composition of the soil [1,2,10]. Changes in soil layer development and properties are primarily related to vegetation regeneration and vegetation persistence [27,[29][30][31]. The regeneration of plants helps the development of the soil layer.…”

The article presents the results of research aimed at growing plants on the basis of different technologies in the relic-swamp salt-sand desert soils of the Aral Sea. The amount of annual precipitation on the soils of this area formed in the conditions of the arid climate region is 180-200 mm. Many factors should be taken into account for growing plants in these areas. It is necessary to choose a suitable halophyte plant for marshy saline soils and to take into consideration sharp changes in temperature throughout the season. Planting in these soils is due to atmospheric precipitation and groundwater. Therefore, experiments were carried out on plant cultivation in the pipe method, and the efficiency was up to 1.5 times higher than in conventional conditions. The combined use of different technologies with the pipeline method has further increased efficiency.

In the article, pollution of saline soils with oil and oil products, physical and water-physical properties depending on the level of salinity are studied. As a result of the research, it is scientifically based that the increase in the level of contamination of the soil is subject to the decrease in water permeability, and the decrease in the level of pollution is subject to the law of the increase in water permeability. In the article, weakly, moderately, strongly and very strongly contaminated soils with oil were studied. According to the results, it was determined that the water permeability of the soil was observed in 25, 45, 45, 37, 5, 3, 2 minutes, and it carried 75, 26, 44, 45, 540, 1050, 1200 ml of water, respectively, for 90 minutes. The amount of water transfer compared to the control soil for 90 minutes was less in 1%, 2%, 5% contaminated soils, and very high in 15%, 25% and 37.5% contaminated soils. The increase in the level of pollution is explained by the deterioration of water permeability and moisture retention. Also, due to the fact that oil is a viscous organic pollutant, the changes of 0.25, 0.5, 1, 3, 5, 7, 10 mm microaggregates, which are important for soil fertility, as a result of pollution, and changes in the amount of these microaggregates were also determined. It was found that the soils around the South Mirshodi oil field were previously contaminated and the amount of microaggregates smaller than 0.25 mm, 0.25 mm, 1 mm, 2 mm and 3 mm in the irrigated soils increased as the distance from the source of contamination increased. This is explained by the decrease in the concentration of oil in the soil. The amount of 5 mm, 7 mm and 10 mm aggregates has decreased. A similar situation was observed around the Kumkurgan oil base. The effect of petroleum hydrocarbons is more noticeable in microaggregates with a diameter of 10 mm.

“…In the formation of sandy soils, of great importance is the specific water regime, in particular good water permeability and capillarity since sand completely absorbs rainwater and water penetrates much deeper. For example: in winter and early spring in Kyzylkum 80-120 mm of precipitation falls; this amount causes wetting of sandy soils down to 1-1.5 m [3,5,7,10].…”

Important problems of improving the animal breeding conditions, microorganisms in soil, and land conditions, preventing desertification processes can be solved by combating drought and desertification, mitigating the environmental situation, sowing drought-tolerant pasture plants in desert areas, studying the biological characteristics of soils to increase plant viability in low-humidity lands, and increasing drought-resistant plant cover in high-drought lands.
