During surface treatment, the density of the 0-30 cm layer of chernozem median was higher by 0.03 g / cm3, and the typed density was the same regardless of the method of cultivation of chernozem for its growth during surface treatment for both upper and lower typical values on 0.02 g / cm3. The coefficient of variation of the structure density during plowing was 1.85 times higher than the surface treatment. The calculation of differential porosity for different methods of cultivation under 5 crops for the 6th year of the experiment showed that in the spring the density of the structure with systematic surface treatment was higher compared to plowing by 0.06 g / cm3, total porosity - by 3 %, and the volume of wells occupied by air was lower by 6.0%. At the same time, the ratio of the volume of wells occupied by moisture to the volume of wells with air reached the optimal level (1 to 1), while during plowing the ratio of categories of wells was in favor of wells occupied by air.
