Abstract： Organic fertilizer can remidate the soil heavy metal pollution， increase the content of soil organic matter and its quality， improve physical， chemical and biological characteristics， increase content of N and P and enhance the soil water retention， fertilizer maintenance and permeability. Organic fertilizer provides the soil with a lot of micro organisms to improve the soil enzyme activity， accelerate the decomposition and circulation of organic nutrients in the soil to realize the sustainable utilization of soil.
