The results of the studies made show that the dried low-lying peat soils used for more than 35 years in the agricultural rotation need nitrogen-phosphorous-potassium feeding in doses calculated for their entering with the crop or by 30% higher than the entering. The content of the basic elements of feeding in these soils is determined by the amount of applied fertilizers, crop level and the mobility (migration mobility) of elements. Complete mineral fertilizer more markedly increases the content of the basic elements of feeding in peat soils. A combined influence of the above factors determines a weak increase in the provision of soil with potassium, calcium and magnesium, to a lesser extent, with phosphorus. A marked influence of mineral fertilizers on the content of mobile calcium and magnesium, exchange acidity is not found
