Abstract: According to the measurement and comparison of phosphorous（P） contents in different depths of the paddy soil applied with different years （0 a， 5 a， 10 a） of spreading manure，the study clarified the characteristics of P accumulation and loss in the paddy soil under the influence of different manure. It was showed that P accumulated in the soil easily， most of which accumulated in the upper part of the 0-40 cm soil and infiltrated from the surface layer migration gradually. P content increased as the increasing of fertilization years. And with the increasing of P content， the capacity of soil phosphorus supply improved while the risk of release P to water increased as well. Therefore， in order to avoid the loss of P element in the soil and to mitigate agricultural pollution， it is necessary to suggest that 5 years should be considered as a continuous interval to apply manure.
