P adsorption and desorption of the different horizons in the albic luvisol with the different additives was studied and compared in this paper. The results showed that the amount of P adsorption by the soil increased as the concentration of the balance solution increased. P adsorption amount of different horizons was in the order of B horizon ＞ the mixing horizon of Aw + B ＞ Aw horizon ＞ A horizon. The increasing rate of P adsorption amount decreased with the increase of the concentration of the balance solution. Applying Ca increased P adsorption amount, the increasing rates of A horizon, Aw horizon and B horizon were 220.16%, 54.50% and 52.36%, respectively. However, applying organic manure decreased P adsorption amount, the reducing rates of A horizon, Aw horizon and B horizon were 70.16%, 45.50% and 55.27%, respectively. P desorption rate will reduce when Ca as the additive but will increase significantly when organic manure as the additive.
