The results of researches received on experi-mental field of chair of Agriculture of State Agricul-tural University of Northern Trans-Urals located in 1.5 km from Tyumen in the village of Uteshevo are given in the study. The soil of experimental field is presented by loam mechanical lixivious cher-nozyom. The researches were conducted after har-vesting annual grasses and spring wheat, plowing (dump way) and loosening of the soil (depleted mode). By the results of the researches of the qualities of the main processing during three years (2014-2016) on average it was found out that the uniformity of plowing and subsurface loosening on the depth was higher when processing on 20-22 and 28-30 cm. The fluctuations in the years after harvesting annual grasses made 98.8-99.4 % on deep plowing and 98.1-98.9 % on small processing and corresponded to excellent assessment. By years of fluctuation of plowing uniformity on 20- 22 cm after harvesting the first wheat varied within 98.4-99.2 %, when processing on 12-14 cm - 98.1-98.8 % which corresponded to excellent as-sessment. The cob and degree of stubble safety were lower on small processing of the soil (12- 14 cm and 14-16 cm). The uniformity of plowing on depth after cleaning of annual grasses and spring wheat corresponded to excellent assessment (98.6-99.0 %). The degree of safety of stubble on average in three years of researches corresponded to excellent assessment after deep processing the soil and good after small processing.
