Biosolvent preparation, bulk, density, deep loosening, water permeability, saline soils, salt leaching.



The effect of deep loosening in the early spring and soil treatment with Biosolvent was studied in this research paper. During irrigation, on the physical properties of gypsum soils and the desalination processes in them. The studies were carried out in the Syrdarya region of Uzbekistan in 3 experimental plots under cotton. Objects of research - saline, compacted, gypsum-bearing soils. Field and phenological observations, soil analyzes were carried out according to generally accepted methods. It was revealed that loosening the soil to a depth of 70 cm contributes to: a decrease in bulk density by 4–9%, respectively, porosity, and also to an increase in water permeability by 3–14 times. This led to an increase in irrigation rates by 350 m3 / ha, with a washing fraction of 9%. Along with a decrease in soil density, this contributed to an increase in cotton yield - 4.6 c/ha. Due to the rupture of capillaries in the soil when loosening, the accumulation of chlorine salts from spring to autumn, in a soil layer of 0-60 cm, decreased by 1.8 times, and with conventional plowing of the soil - increased by 2.4 times. When loosening gypsum soils to a depth of 70 cm, the bulk soil mass decreased from 1.60 g/cm3 to 1.20-1.36 g/cm3. When spraying heavily salted loose soil with Biosolvent before watering the cotton, the leaching of the toxic chlorine ion by irrigation reached 90%. The combination of deep loosening of the soil with the Biosolvent preparation is recommended for land reclamation of the Hungry Steppe lands.
