Effects of application of chemical fertilizers on bioavailability of heavy metals in soil
化肥施用对土壤中重金属生物有效性的影响研究

The availability of heavy metals to plants is one of the topics in the study of environmental science.This paper by using the recent achievements,presents an overview on effects of chemical fertilizers on availability of heavy metals.Fertilizers can alter soil properties such as pH,ionic constituents in solution and CEC or can directly react with heavy metal ions.All these effects would change the forms of heavy metals in soil and the absorbing process of plants.Therefore,when applying fertilizers to soil,their types and their rates should be considered,especially for heavy metal-contaminated soils.
