In field experiments in the Moscow region in 2015-2017, the efficiency of phosphorus fertilizers for cultivation of the high productive spring barley variety Nur on differently cultivated soddy-podzolic loamy soils was studied. The following variants were compared: no fertilizer (control); N60K60 (background); as well as background + P30, P60, P90 and P120 were compared in a short-term experiment. The high efficiency of phosphorus fertilizers on the poorly cultivated soil (pHKCl 3.9-4.2; P2O5 35-60 mg/kg) with low content of mobile aluminum (40-48 mg/kg) was established. On cultivated soil (pHKCl 5.1-5.7; P2O5 95-140 mg/kg) with a low content of mobile aluminum (13-19 mg/kg), the highest rates are achieved with a lower dose of phosphate fertilizers than on poorly cultivated soil. On poorly cultivated soil with a high content of mobile aluminum (about 130 mg/kg), due to the systematic use of nitrogen and potash fertilizers, the effectiveness of phosphorus fertilizers increases by liming. The maximum yield on average for 3 years (5.70-5.78 t/ha) is achieved on cultivated soil by applying P60, P90, P120, but the payback of fertilizers did not exceed 2.18 rub/rub. The high payback (3.37 rub/rub) was obtained on poorly cultivated soil by applying P30, the yield was 4.23 t/ha.
