An important agronomic task in cultivating spring rape is improving the physical properties of leached black soil, which are extremely important for increasing its productivity. A central role in the physics of these soils is played by studying its density, which helps regulate the soil processes and maintain favorable conditions for spring rape. According to the studies, the highest productivity of spring rape is observed in the case of the arable layer density of 1.00 – 1.10 g/cm. Moreover, in the case of soil density of 1.10 g/cm, productivity is better by 5.6 – 8.5 % than in the case of 1.00 g/cm. The number of seeds per pod has increased especially strongly (by 13.8 %). In the subsurface layer (30 – 40 cm), soil density of 1.10 – 1.20 g/cm is optimal for spring rape growth and development.
