摘要:
Soil organic matter (SOM) and pH are not only an important part of soil fertility,but also a source of nutrients for plants and an energy source for the life activities of soil microorganisms(Huang,2000).Moreover,soil organic matter (SOM) has a great impact on soil properties and can improve soil fertility and buffering performance.Therefore,the contents of soil organic matter and pH are important indicator to measure soil fertility
