Experiance was taken on soil- typical chernozem. Analysis receiving results show that in the end of the rotary, average about layer 0-40 cm compactness of soil g/cm3 increase with 0,19 g/cm3; 0,13 g/cm3; o,7 g/cm3 and 0,9 g/cm3, and total soil's air derease with 7,08%; 4,81%;3,95% and 3,58% about systems A1, A2, A3,A4. Soil's hardness kg/cm2 change depending on soil cultivation and it's moisture. In the end rotary hardness phase in the soil increase main at expense moisture content. Gaseous phase decrease for systems A1 and A4 , and for A2 and A1 its keep persistent in comparison with starting facts.
