Influence of long-term fertilization on phosphorus fertility of calcareous soil I Organic matter,total phosphorus and available phosphorus

XIE Linhua 1,L Jialong 2,ZHANG Yiping 2,LIU Xuanwei 2,LIU Lihua 2 ( 1Environmental Engineering Teaching and Research Section,Shannxi University of Science and Technology,Xianyang 712081,China; 2National Key Laboratory of Soil and Water Erosion and Agriculture,Northwest Sci-Tech University of Agriculture and Forestry,Yangling 712100,China).  
A 23 years-located experiment of wheat-corn rotation showed that long term application of animal manure combined with chemical fertilizer contributed greater to the contents of soil organic matter,total phosphorus,inorganic phosphorus and available phosphorus.Applying chemical fertilizer could increase soil organic matter,total phosphorus,inorganic phosphorus and available phosphorus contents,but the increment was lower than treatments animal manure and fallow.Compared with no fertilization,different fertilization treatment had its own distribution characteristics of soil organic matter,total phosphorus and available phosphorus in 0~100 cm soil layer.
