Abstract
Salts in the composition of the soil, especially soluble, have a serious impact on the development of crops, can dramatically reduce their yield.The results of leaching on salty soil in Bukhara oasis with the help of chemical component Biosolvent (ChCB) and its effect on effectiveness of leaching is given in this article.As a result of the analysis, the degree of soil salinity was determined: the soil is moderately saline, refers to chloride-sulfate salinization.Washing works on the experimental field were performed on January 9-24, 2017. In the experimental field, the highest leaching rate was registered in the traditional method used in the farm, with this option the seasonal leaching rate was 3,986 cbm/ha, 2 washes were performed during the season. In the 2nd option, the washing work was carried out using ChCB, and tested in accordance with their recommendations, in which the leachingrate was reduced by 30%, which amounted to 2447 cbm/ha, while washing was performed 1 time. In option-1 of the experiment, the leaching rate was calculated according to the formula by V.R. Volobuev and amounted to 3492 cbm/ha, and this rate was fed in 2 steps.
