The dependence of the crop-producing power of fodder crops from the levels of groundwaters and the content of the organic matter. Based on the received experimental and calculation data the effective structure of sowings for each of considered soil varieties was developed on three levels of reclamation, such as normal, below normal and above normal. It is shown that on the all arable lands regardless the hydrological and agrochemical properties it is possible to create the structure of the sowings providing for balanced fodders in energy and protein required for receiving the average annual yield of milk equal to 5000 kg from a cow. It is established that conditional profit to a great extent depends on hydrological and soil conditions. The analysis of the obtained results showed that for the creation of the effective structure of using arable lands it is necessary to adapt species composition on fodder crops to hydrological and agrochemical characteristics of a field. Aimed to receiving balanced fodder it is necessary to consider all the aggregate of soil conditions of arable lands
