Abstract

Abstract: The distribution and relationship of Olsen-P,CaCl₂-P,NaOH-P were studied in the profile of 0-100cM vegetable fields.The results showed that the content of Olsen-P,CaCl₂-P,NaOH-P was 123.8-399.6mg/kg,9.1-27.2mg/kg and 184.9-608.9mg/kg respectively in the profile of 0-20cM layer.The most of phosphorus in the soils was accumulated in the profile of 0-20cM layer and the content of Olsen-P,CaCl₂P,NaOH-P was decreased graduaily with the depth of soils.There was significant positive correlation between Olsen-P,CaCl₂-P and NaOH-P.The content of CaCl₂P was increased significantly when the content of Olsen-P was more than 55.6~63.0mg/kg.The content of Olsen-P was the "Change Point" of indicating the risk of phosphorus leaching.

Key words: Vegetable fields, Phosphorus leaching, Impact factors
