Soil physicochemical properties of Huoditang in different altitudes were researched for exploring the relationship between altitude and soil physicochemical properties.Stratified to get soil sample,the content of soil organic matter,total nitrogen,available nitrogen,total phosphorus,available phosphorus,total potassium,available potassium and pH were determined.The results showed that:(1) With the increase of section depth of soil samples in the different altitudes,pH appeared gradually increase,but the con...
