Winter wheat straw was decomposed by a strain of cellulose-fermenting mycromycete (CM) extracted from leached chernozem. The straw was decayed by 55-75% if the concentration of CM was 4300 spore per ml over a nutritive additive (NA) and nitrogen. In the field experiments sugar beet was grown on leach semi loamy chernozem according the conventional in the Central Chernozem Zone technology. The test variants of straw applying were i) straw alone; ii) straw and nitrogen at a reactant dose of 40 kg per ha; iii) straw and NA; iiii) straw, NA, nitrogen and CM. Ammonifier number increased by 26%, humus synthesis speed did in 2-3 times, total micromycete number also grew up under CM action in the soil at the beginning of sugar beet vegetation. The CM precipitated the seedling emergence and raised their density. At the stage of the 1 leaves 100 plant weight increased by 1.6% and Pythium disease of beet prevalence was 17.6% (the control meaning was 21.0%) under CM action. The addition yield was 2 600 kg per ha and the sugar output increased by 500 kg per ha when i variant was applied. At the iiii variant applying the yield increased by 12 500 kg per ha, saccharinity did by 0.4% and the sugar output did by 2 200 kg per ha. So, straw ploughing together with CM, NA and nitrogen would contribute straw decomposing and soil fertility preserving at simultaneous crop productivity growth and environment pollution decrease
