IMPROVING THE PHYSICAL AND AGROCHEMICAL PROPERTIES OF IRRIGATED GRAY-MEADOW SOILS USING VARIOUS PLANT RESOURCES

Аннотация

The article presents the re sults of scientific research aimed at increasing the fertility of irrigated gray-meadow soils in the Mirzachul oasis by planting various green manure crops. As a result of planting green manure crops, the soil has become enriched with organic residues, and the humus content has increased to some extent. The soil density has decreased, its porosity has improved, and there have been positive changes in the amount of mobile nutrients in the soil. Consequently, the yield of crops planted after the green manure crops has increased to a certain extent.
