Abstract:The impacts of the associated toxic constituents such as Cd,Chloral and radioactive elements on the soil environments and crop products are expounded.Cd content standard of soil,crop and fertiliaer are also discussed.Cd pollution of general farmland isn‘t existence in short-term,but fertilizer pollution must be paied attention to in area and special crop for long-term applied phosphate fertilizer.Radioactive impurity in phosphate fertilizer can‘t cause pollution of soil.Chloral contente in phosphate fertilizer must be control umder crop‘s critical dosage and assist fertilizer rationally.The strategies for overcoming these impacts are also discussed.
