英文摘要：

Colloids play a key role in the transference process of phosphorus （P） in soil. Activation and transference of soil colloidal phosphorus have great effect on soil P pool and the surrounding water quality. This paper summarized the current studies on soil colloidal P, discussing the effects of the various factors （e.g., soil physical and chemical properties, fertilization, rainfall and soil amendments） on the transference of soil colloidal P. Some advanced analysis technologies （e. g., flow field-flow fractionation, transmission electron microscope-energy dispersive X-ray spectrometer, X-ray absorption near-edge structure and nuclear magnetic resonance） and methods of reducing soil colloidal P were also involved. This review would provide important information on the mechanism of soil colloidal P transference.
