Today the water resources have a strategic impact in Bukhara region of Uzbekistan and about 95% of agricultural products produced in irrigated areas of the region. Conservation and efficient use of water resources is imperative. The goal of this research is to provide farmers scientific and practical recommendations on enhancing the soil leaching efficiency and improving the ameliorative condition of arable lands by using Biosolvent chemical compound during the soil leaching. Salts in the composition of the soil, especially soluble, have a serious impact on the development of crops, can dramatically reduce their yield.As a result of the analysis, the degree of soil salinity was determined: the soil is moderately saline, refers to chloride-sulfate salinization. When, soil leaching is carried out by Biosolvent chemical compound at the medium salted soils in Kagan district of Bukhara, the process of salt dissolution in soils accelerated and consumption of water used for soil leaching was saved up to 30% due to the enhancing the soil leaching efficiency.

The study of sedimentation processes in the clarifiers in the drip irrigation system was carried out in the fields of farms in the Bukhara, Kogon, Peshku, and Romiton districts of the Bukhara region, which are supplied with water from the Amudarya river. During the research, methods of field observation, generally accepted methods in hydraulics, and methods of comparing experimental results with hydraulic calculations were used. Hydraulic calculation of turbid sedimentation process in sediments was performed by A.G.Khachatryan method. As a result, a graph of the relationship between the settling length and the settling rate of the mud in was developed for different water consumption. As the length of the settling tank increases, the settling rate of the mud increases, i.e., the settling rate of the 41 m long settling tank is 30-40%, while that of the 800 m length is 70-80%. If 20 ha of land is irrigated in 6 plots, then 3.33 ha of land is irrigated in each plot. The water norm required for 1 irrigation of cotton on 3.33 ha of land is 900-950 m3, while the average is 250-300 m3 / ha. If 2 chambers with a length of 10 x 40 m (depth 2-2.5 m) are taken in each chamber, then in the first chamber, 35-40% of the distilled water passes into the second chamber, and in 8 hours, it becomes another 35-45 %, and clear water can be sent to the irrigation system through pumping units. In such cases, water should be constantly supplied to the first chamber from the ditch until the end of 1 irrigation of 20 ha.
