Abstract

The article is devoted to solving the problem of re-compaction of agricultural soils. The positive effect of growing six species of perennial grasses has been shown: sowing alfalfa, meadow clover, sand sainfoin, white clover, horned clover, eastern goatskin on the creation of an optimal bulk soil mass. The indicated indicator in the dynamics of the four-year period of growing leguminous perennial herbs is analyzed. The minimum period for growing leguminous perennial herbs has been established for which it is possible to achieve a stable and favorable bulk soil mass. The factors providing the optimal soil density during the cultivation of certain types of herbs, including the parameters of the root systems, soil cultivation and weather conditions, are justified. Based on the studies, a technology was developed to optimize the volumetric mass of the soil by selecting certain types of perennial leguminous herbs and the timing of their cultivation. The ability to optimize the bulk soil mass at the level of 1.13 – 1.18 g/cm3 for the third or fourth year of vegetation of leguminous perennial grasses has been proved.Іn the year of sowing of leguminous perennial grasses, the volume of soil mass depends largely on the basic tillage of the grasses under sowing and is determined by the magnitude and nature of precipitation. Since the second year of vegetation of leguminous perennial grasses, the bulk mass of the soil is determined by the peculiarities of propagation in the soil of the root systems of different types of grasses. There is a tendency to decrease the volume of soil under the legume of perennial grasses in the second year of their vegetation, followed by an increase in the third year and stabilize – in the fourth year of vegetation of grasses at an optimal level for the growth and development of cultivated plants. Among the perennial grasses, the soil of alfalfa is sown best, and the worst is sand asparagus.
