THE INFLUENCE OF GREEN MAMURE CROPS AND SPRING GRAINS ON SOIL AGROPHYSICAL PROPERTIES IN CROP ROTATION LINK WITHIN IRRIGATION CONDITIONS IN TERSK-SULAKSK SUBPROVINCE

Based on the analysis of literature data and scientific research, this paper considers the problem of conserving and maintaining soil agrophysical properties such as density and porosity as important criteria that determine soil fertility, applying green mamure crops (seed peas, spring rape, amaranth), as well as spring grains (grain maize, grain sorghum). according to the results of the analysis, the best agrophysical properties were found in plowing up seed peas and amaranth and applying fertilizers where the average density was 1.20–1.21 ha/cm3, respectively. here, increasing soil density in comparison with other options, occurs in the range from 0.03 to 0.05 ha/cm3. the average values of soil porosity, when cultivating crops, according to the experimental options, varied in the range from 51 to 54 % and were estimated as "satisfied".
