We have tried the nutrient value of the phosphorus in the defluorinated phosphate created in Japan to wheat in pot experiments and obtained the following results. (1) Nutrient value [table] As for the nutrient value of the phosphorus, in the light P_2O_5 case the defluorinated phosphate was inferior to superphosphate, but in the heavy P_2O_5 case obtained the same results as the fused phosphate and Thomas phosphate had. (2) The absorption of the phosphorus in the defluorinated phosphate reached to 23.86% together with ears, stalks, leaves and roots, therefore as regards the absorption of phosphorus the defluorinated phosphate is a slight superior to superphosphate, fused phosphate and Thomas phosphate.
