On the average for 2006-2007 years of research the tendency in increase of productivity of spring triticosecale at liming soil by dolomite and chalk is observed. Use the carbonate sapropel authentically raises productivity of culture, it has happened due to complex action of meliorant. Application of potash fertilizers into a dose of 70 kg/ha on the background of liming by dolomite provides gain productivity of triticosecale up to 2,4 c/ha. Increase in dosage of potash fertilizers to 90 kg/ha does not render authentic influence on productivity in comparison with variant N80P60K70 + dolomite. Application of 120 kg/ha on the background of liming by dolomite provides authentic increase in productivity of spring triticosecale to variant N80P60K70 + dolomite - 4,3 c/ha. Research carried out on sod-podzolic light loam soil have shown that the content of basic elements of nutrition (nitrogen, phosphorus, potassium, calcium, magnesium) in basic and side production has slightly been changed and in a greater degrees depended on level of mineral nutrition. The general removal of nitrogen, phosphorus and potassium has authentically increased at application of limy materials, higher doses of potash fertilizers. Calcium removal had the maximum value in variants with application of chalk and carbonate sapropel. Magnesium has been removed with yield from 5 to 7 kg/ha. As a whole liming has smaller influence on chemical compound of plants, than application of mineral fertilizers. Liming did not render negative influence on spring triticosecale and had no expressed certain influence on quality of plant production
