Abstract: The effects of long-term fertilization on inorganic phosphorus fractions in lime concretion cinnamon soil were studied using the fraction classification developed by Gu Yi-chu and Jiang Bo-fan.The results show that Long-term application of chemical phosphorus and manure fertilizer may increase the inorganic phosphorus.The main of inorganic phosphorus in cinnamon soil is Ca-P which takes up 80.0%,in the next place are O-P,Fe-P and Al-P.Under the Long-term application of chemical phosphorus and manure fertilizer,the components pool of inorganic phosphorus have increased compared with non-fertilization,except of nitrogen fertilization.In inorganic phosphorus,the related coefficient between Ca2-P,Ca8-P,Ca10-P,Al-P,Fe-P and Olsen-P are 0.976 7,0.886 5,0.915 5,0.860 2,0.848 4,which reach significant positive relationship,except O-P.Ca2-P,Al-P,Fe-P and Ca10-P are the main sources of Olsen-P can be found by path analysis.

Key words: Long-term fertilization, Cinnamon soil, Inorganic phosphorus forms
