Abstract:: To understand the soil nutrient status Xinjiang pomegranate main producing areas.Laboratory analysis of pomegranate orchards soil in different ages 0-20 cm,20-40 cm range of soil organic matter,total nitrogen,available nitrogen,P and K were determined.The results showed that the range of soil organic matter with different soil depth and different age were between 0.576 0-0.659 5 g?kg-1,0.402 5-0.504 0 g?kg-1, mean range were 0.617 8,0.453 3 mg?kg-1, separately. The range of soil total nitrogen were 0.069 5-0.072 5 mg?kg-1,0.058 5-0.060 5 mg?kg-1, mean range were 0.071 0、0.059 5 mg?kg-1, separately. The range of soil available nitrogen were 54.079 0-63.106 0 mg?kg-1,52.091 0-57.153 5 mg?kg-1,mean range were 58.592 5,54.622 3 mg?kg-1, separately. The range of soil available phosphorus were 32.362 5-36.704 0 mg?kg-1,19.683 5-22.042 5 mg?kg-1, mean range were 34.533 3、20.863 0 mg?kg-1, separately. The range of soil available potassium were 309.088 0-395.853 2 mg?kg-1，301.294 2-365.353 0 mg?kg-1,mean range were 352.470 6,333.323 6 mg?kg-1, separately. After testing analysis found that,in addition to pomegranate orchard soil outside the high potassium content,organic matter,total nitrogen,available nitrogen was low,medium available phosphorus,pomegranate soil nutrient imbalances in soil for future pomegranate rational fertilization provide a scientific basis.
