Plowing under all predecessors except black steam contributed to better use of moisture from the autumn-winter period. Precipitation was the worst used to replenish soil moisture during shallow tillage - by 26.9-39.4% in 2020 and by 8.5-18.2% on average over five years. In winter wheat crops during the autumn-winter period, the most moisture accumulated after sidereal steam - 22.4-35.6 mm, and the least - after black steam - 0.1-11.8 mm. After non-steam predecessors, the most moisture accumulated during deep tillage, and the least - during shallow tillage. The density of soil composition in the layer of 0-40 cm under winter crops is 1.27-1.31 g / cm3, and under spring slightly higher - 1.30-1.35 g / cm3. The yield of all crops was highest in the six-field crop rotation with black steam. Systematic plowing promotes the formation of higher yields compared to other tillage options.
