It is shown that the application of high doses of organic and mineral fertilizers (N 60P 60K 60+60 t/ha manure) and plowing under vetch and oats as green manure makes it possible in low-humified agrozems to reduce soil acidity by 0.5-0.6 pHKCl units, increase total exchangeable bases by 3.1-4.3 mmol/100 g soil, and increase organic matter content by 0.32-0.41%. This variant can be the basis of the technology of rehabilitating low-humified soils, since it provides a substantial increase of their fertility at a relatively low cost.
