The change of soil fertility in crops Galega orientalis Lam. under the influence of different techniques of tillage (harrowing, disking) with the addition of various doses of mineral fertilizers was considered. In the harrowing of soil fertilization intensified the processes of humification. The contents and stocks of humus increased. When disking the soil the contents and stocks of humus in the control and in variants with application of mineral fertilizers decreased to low values. The reserves of humus in the application of mineral fertilizers was low. It was found that the most effective way agrotechnical treatment artemgukasov gley soil with the sowing of the vetch is harrowing, with the application of mineral fertilizers. These variants have fulvate-gumaty and humany type humus average degree of humification of organic matter, higher maintenance and inventory quasarsphere microbiological processes of mineralization of organic matter. The application of mineral fertilizers on the background of the harrowing protects the humus from digestion by the microflora, as evidenced by a drop in the total mineralization.
