It was established that there is no necessity in the annual tillage in crop rotation. Reduced cultivation helps not only to get the same amount of produce as the annual one, but also increases in mass of residues, accumulation of feeding elements in it, and so increases in soil fertility. Economically valuable share of the crop is more that the mass of residues. Organic and mineral fertilizers, increasing in crop yield and carrying out of nutrients, make at the same time the big impact on soil. They fill up stocks of food elements, increase weight of root residues, the content in them of nitrogen and cindery elements, considerably is changed by agronomical properties of soil. In general, residues cannot provide full reproduction of organic matter in soil and eliminate the deficit of easily broken organic compounds and mobile forms of feeding elements
