Rehabilitation of heavily eroded soils by fertilization and cultivation of perennial herbs. It has been experimentally established that in an efficient anti-erosion framework of agricultural land by using fertilizers and cultivating perennial grasses within 6-8 years, it is possible to restore the humus content of arable highly eroded chernozems. For six years, the humus content has increased from herbs by 13%, and from herbs and fertilizers by 19-26%. The share of fertilizers in the total growth of humus ranged from 35 to 54%. Compared with manure, the annual application of N60P60 has significantly increased humus. With an increase in the dose of manure from 50 to 200 tons / ha, the increase in humus decreased from 50 to 35%.
