The implementation of the No-till system for surface cultivation ensured stable differentiation of the cultivated soil layer (0-30 cm) according to the density of the structure according to the principle of 1.12 g/cm3 (loose) - 1.23 g/cm3 (compacted) - 1.20 g/ cm3 (decompressed). The overall crack density varied inversely: 57% - 53% - 54% for the ratio of crack categories with moisture and air 0.7 to 1 - 1.0 to 1 - 0.9 to 1 with the most optimal value of Kstr, which was at the level of Kstr= 1.35 (0-10 cm) and Kstr=1.15-1.16 (10-30 cm). Among all the parameters, the ratio of the volume of the aeration slits is the most effective. It turned out that when abandoning plowing per unit of increase in the density of the structure, the optimization of the ratio (1 to 1) increases by 1.81 times for plowing No-till systems, 1.98 times for surface cultivation, and for No-till systems for surface processing - 2.68 times. At a density of 1.21 g/cm3, the ratio varies in the order of growth of 0.75 to 1, 0.85 to 1, 0.90 to 1, and 0.95 to 1, respectively.
