Effective soil leaching technology in salined fields

Relevance One of the main factors negatively affecting agriculture and the environment in Uzbekistan is soil salinization. Methods In this article given the results of field experiments on improving leaching technology in the salty fields of Bukhara oasis with using chemical component Biosolvent. Scientific researches were carried in irrigated fields of scientific-research center of Tashkent institute of irrigation and agricultural mechanization engineers Bukhara Branch (TIIAME BB) which is located in Bukhara region, Kagan district, during 2017-2019 years. Results Leaching saline soils with using Biosolvent reduces salt content in the active soil layer from 0.376% to 0.204, while desalinization ratio will be 1.84. With this technology leaching norm was 30% less compared to the control.
