Study on technological properties of winter wheat soils

The aim of the study is to and analyze physical, mechanical technological properties soils from under winter grain crops in hot climate Uzbekistan. results determining moisture content, density, hardness resistance various deformations after harvesting wheat are presented. basic principles methods classical mechanics, mathematical analysis statistics were used this study. Studies have found that, layer 0-30, soil for ten days cereals decreases by 12.1-16.3%, increases 10.7-16.4% 3.22-5.14 MPa. At same time, at an average humidity 12-14%, breakage torsion, respectively, 1.3-1.8 1.0-1.1 times higher than shear. shear 87.9 kPa, torsion-69.7 78.6 respectively.
