| Abstract | The issues of recoupment of phosphorous fertilizers, that are the most disputable in agronomy because of the determined necessity in fertilizers and their economic efficiency of usage, were studied. It has been presented, that recoupment of fertilizers is a complex and not constant value for different crops. It has been established that at a price for grainy superphosphate of 11000 UAH /t and the cost of its use in optimal doses for field crops on the basis of a balanced nitrogen-phosphorus nutrition, the cost of an increase in yield is 2153-25194 UAH/ ha. Payback (unprofitableness) of 1 kg. phosphorous fertilizers varies in a wide range - from - 40.0 UAH to 346,2 UAH, depending on the crop. The limit of the unprofitable price per unit of the active substance of phosphorous fertilizers at the optimal dose of application depends on the crop and is in the range of 25–417 UAH/kg. With the current disparity in prices for crop products and grainy superphosphate, its use is unprofitable for winter rye, spring barley, grain sorghum and sugar beet (when applied against a background of 40 t / ha of manure). It is due to the availability of graded chernozem with mobile potassium compounds, biological characteristics of crops and technologies for their cultivation | ||
