In this experiment, characteristics of phosphorus fixation and release were studied with added different concentrations of P (water∶ soil is 20∶1) and by sequential extraction. The results showed that, fixing P capacity of red soil is higher than that of fluvo-aquic soil, and fixing P capacity of paddy soil is lowest among three soils. Fixing P capacities of three soils are 2.84 g kg -1, 2.53 g kg -1 and 2.08 g kg -1 soil under treatment of P 2.97 g kg -1 soil. Ratio of P fixed to P added reduces with increase of added P. In release experiment, capacities of P release reduce with increase of extracting times, and change insignificantly after 8 times of extraction. In three soils, maximum of P release of paddy soil (124.07 mg kg -1) is higher than that of red soil (60.46 mg kg -1)and fluvo-aquic soil (19.74 mg kg -1), the similar results were obtained in total amount of P released. At the beginning of experiment, the ratio of P released to P fixed increases gradually and then reaches equilibrium with increase of extracting times, and that of P released in paddy soil is higher significantly than that of red and fluvo-aquic soils. Ratio of P released to P fixed of soils treated with 1.98 g P kg -1 soil is higher than that of soils treated with 2.97 g P kg -1 soil in paddy and fluvo-aquic soils, but the contrary result was obtained in red soil.
