The equilibrium limited absorpbing hours of phosphorous is 16 and the optimum limited one is about 24. The soil absorpbing amount of phosphorous was increased to 0.5-0.7 mg/100 g of soil when soil temperature had been increased as 5 degC, 0.46 mg/100g of soil in accordance with the increasement of soil humidity by 7 percent, otherwise, no significant difference at over 70 percent of soil humidity. Phosphorus was absorbed less 9.5 percent in phosphate ammonium and 9.7 percent in superphosphate by the increasement of soil particles from 0.001mm to 0.25mm
