aref2 Experiments were conducted in 2009-2020 in the Udmurt republic. The broken soil of the experimental plot is agrarian texture-differentiated heavy loamy land having a low content of humus and increased total exchangeable bases. Background soil is sod mean podzolic weakly washed mean loamy soil. Application of the increased doses of fertilizers (N60P60K60 + a manure of 60 t/hectares) and covering a green manure of legume-grass mixture allow to increase the content of mobile phosphorus - on 13,6-16,2%, an exchangeable potassium - on 12,4-19,4%, and organic substance - on 16,0-17,3%, yield spring wheat in 1,9 times at the disturbed sod-podzolic soils. This variant is taken as recultivation technologies of the upset soils. This variant provides increasing the fertility of the disturbed soils with rather low expenses.
