In this paper, phosphorus sorption and desorption in Albic soil were studied under long- term fertilization. The results indicated that the phosphorus absorption curve of tested soil accords with the formula of langmuir. The capacity of absorbing phosphorus in low concentration was strong, but with the increasing of phosphorus concentration, that of absorbing phosphorus became week. In different fertilization treatment, the maximum phosphorus sorption in no fertilization treatment was the biggest, that of the treament of applying manure was the smallest. The change of eguilibrium constant was little, the value was 0.2 or so, that of the maximum phosphorus sorption was large. The trend of phosphorus sorption in different fertilization treatment was all that the phosphorus sorption capacity increase with the increasing of phosphorus concentration, then become steady. Applying manure made the capacity of absorbing phosphorus decline, but that of desorbing phosphorus enhancd; no fertilization made the capacity of fixing phosphorus to ascend.
