The paper presents the effect of various fertilizing ameliorative means (FAM) making from local industrial and agricultural wastes and mineral fertilizers on ordinary degraded chernozem features. After three years from their applying soil sodicity and alkalinity were decreased but soil nutrition for growing crops wasn’t optimal. In order to get planned yield the additional applying of fertilizers is required. The conducted study established that variants with FAM required the decreasing of nitrogen fertilizers by 15-27 %, phosphorus – by 13-23 %, potassium – by 14-25 % against control variants without FAM but with applying of mineral fertilizers for planned yield.
