The results indicated that the soil treated by PAM led to decreasing of phosphorus adsorption. When the PAM dosage was low, the higher the PAM dosage was, the less the adsorbed amount was, and the minus correlation showed between them was highly remarkable. The aximum adsorption amount(Xm) of %、%、%PAM amneded soil was ugg1, ugg1, ugg1, lower than the Xm of CK which was ugg1. Atthe same time, the adsorption intensity was not only weakened but strengthened. Because PAM affected the slowness adsorption by altering the soil property, while had no remarkable effect on speediness adsorption.Key words: PAM；adsorption；phosphorus concentration；soil property
