Results of researches of influence of security of sod-podzolic sandy ground mobile and rate of potash fertilizers on economic efficiency of their applcation in crop rotation with the following alternation of cultures are resulted: corn on green weight, a spring wheat, a mix, winter. It is established that at cultivation of agricultural crops in a part of a crop rotation, for reception of the maximal productivity, at the first level the high doze of potash fertilizers (120 kg/ha), the second - average and high (90 and 120), the third - minimal (69 kg/ha) is the most effective. At the fourth level of the contents mobile potassium application of potash fertilizers is inexpedient
