In this work, the presence of soil moisture in the system of 70-75-65 %relative to the FPV before drip irrigation of winter wheat reduced the phosphorus content against the background of N-187,5; Р2О5-131, К2О-93,7 kg/ga, reducing the norms of mineral fertilizers in winter wheat top dressing by 25%. The amount of available phosphorus and nitrogen in the soil is 6,3-11,0 mg/kg, the increase in efficiency is up to 25 %, as well asdata on the yield of winter wheat.
