Abstract: The purpose of this study was to clarify the law of phosphorus (P) accumulation and runoff with long-term P fertilization in paddy soils. Total P,soil organic P,and available P with long-term (10 years) pig manure fertilization were studied in Jiaxing,Zhejiang Province,China using correlation analysis and significance analysis. Results showed that after 10 years of pig manure fertilization soil total P tended to decrease ,and phosphorus moved to the 40 cm soil layer . Also,soil organic P increased from 212 to 248 mgkg-1 with a significant (P < 0.05) correlation (r = 0.811) between soil organic matter and soil organic P. Additionally,soil available P increased with pig manure application. In areas with high levels of soil P,pig manure fertilization increased soil P accumulation and movement. Finally,soil P was greater than the vigilance value of the environment implying risk of a soil P release to the water. [Ch,5 fig. 1 tab. 21 ref.]
