Abstract
The highest productivity of cultures in a crop rotation link on sod-podzolic soils is received at organic mineral fertilizing system providing entering of mineral fertilizers (mid-annual dose N110Р60К120) against a background effect and aftereffect 40-60 t/ha of straw manure. On light loamy soil productivity has made 110,3-114,1 c/ha of fodder units (f.u.) at payment of 1 t of manure on the average 25,0 f.u. , 1 kg NРК - 9,1 f.u., on friable sandy soil the given parameters were at level of 111,4-116,9 c/ha 50,1 f.u and 9,2 f.u. accordingly. On sod-podzolic soils the net profit has made 701-984 thousand roubles at profitability of 88-106 % in variants with the maximum productivity. Mid-annual economic nutrition elements removal at cultivation of a crop rotation link on sod-podzolic soils was 143,4 kg/ha of nitrogen, 76,8 kg/ha of phosphorus, 122,6 kg/ha potassium, 36,9 kg/ha of calcium and 27,3 kg/ha of magnesium in the middle.
