In work the information on productivity of agricultural crops in conditions by security a moisture is resulted. It is informed, that reception of high and stable crops probably by application of ways of the processing providing accumulation and a rational expenditure of a moisture. It has been carried out research on studying various ways of processing of ground and mulchiring on efficiency of corn on a silo. With interesting variants the scheme is developed for deep studying the put questions. The Significant amount of deposits for the two first years month provided maintenance of humidity of ground within the limits of optimum values. Mathematical processing of dependence of size of productivity from annual quantity of deposits is lead. The difference in stocks of a moisture between variants of experience has decreased, but, nevertheless, a little bit more it was kept on allotments with mulchiring. Absence of rains has led to full loss of an accessible moisture, and even to a part of a dead stock in an arable layer during cleaning by all variants of experience with that only a difference, that on variants with mulchiring losses were three times less. Thus, low stocks of a moisture in ground by time of crop, the hot and dry summer was reflected in productivity of corn. It is informed, that especially contrast distinctions in a year were at a drain of thawed snow. The expenditure of an accessible moisture during vegetation of corn in many respects was defined by putting weather and climatic conditions of concrete year.
