| Abstract: | [Objective] The research aimed to increase soil fertility and promote ecological recovery.[Method] Main fertility indexes of soil around the landfill were measured in eastern suburb of Kunming.[Result] The types of soil texture were loam,and the soils around landfill were acid,short of nitrogen and phosphorus,but rich of potassium.[Conclusion] The quantities of organic fertilizer,chemical nitrogen and phosphorus fertilizers should be increased,and potassium fertilizer should be supplied properly to restore the ecology. |
