It was found that long-term cultivation of perennial cereal bioenergy plants has a positive effect on the fertility of low-yielding soils. Thus, for the cultivation of switchgrass for nine years, the content of organic carbon in the soil increased from 1.87 to 2.40%, and for the cultivation of giant miscanthus for six years from 1.87 to 2.42%. Conclusions. Laying plantations of perennial cereal bioenergy plants on low-yielding and erosion-prone lands helps to restore their fertility and provides a sustainable supply of high quality feedstock for the production of biofuels.
