Influence of mineral, organic and organic-mineral systems of fertilizers on biological activity of ground and productivity of potato was studied in 2006-2007 on a background of its processing with use of plowing. The comparative estimation of biological activity of ground is given at anthropogenous intervention and in natural conditions. The organic and organic-mineral systems of fertilizers were the best for the average of development of bacteria and fungi, optimum for actynomycetes-mineral and organic-mineral. Parameters of number of the Investigated groups of microorganisms in the virgin control were higher than in agrophitocenosis. Investigated systems oj fertilizers did not differ authentically among themselves on influence on productivity of potato but in comparison with control variant essentially raised productivity. The increase has made about 100 c/ha in 2006, about 160 c/ha in 2007
