H.  aYield increasing of soybean on the newly reclaimed hillside land through phosphorus fertilizer management.  c1989  ap.734-739. t.2  vt.2  aTo increase soybean products, soil P and P-fertilizer management was investigated in the farmer's field. One experiment was an attempt to determine the optimum levels of P-fertilizer application for soybean on the 22 farmers' fields of newly reclaimed soils and the other was to evaluate the broadcast and band application effects of P-fertilizer under under soybean-barley cropping system on the sandy loam soil. The optimum application rates of P-fertilizer were ranged from 120 to 850 kg per ha as P2O5 and an equation form phosphorus recommendation was obtained from the relationship between the abailable P2O5 in soil and the amount of P-fertilizer applied. The broadcast application of P-fertilizer was superior to band in view of soybean yield and the soybean yield was the highest in the broadcast with the amount 380 kg P2O5 per ha based on soil testing and thereafter addicitonal 60 kg at the every crop period. In the soybean yields of three years, the maximum yield, 3,220 kg per ha, was obtained at 220 ppm of available phosphate under boadcast and 2,590 kg at 200 ppm under band application.  aphosphorus  aFertilizante  aFósforo  aRendimento  aSoja  aCoreia  aFertilizer  aKorea  aSoybean  aYield1 aLEE, C.
