摘　　要：Phosphorus (P) is one of the three most important elements that support the growth of crops. The fixation of P by iron (Fe) and aluminum (Al) oxides is a main reason for low phosphorus efficiency in variable charge soils. Previous studies on the mechanism of P fixation on soil surfaces were mainly performed through the routine chemical analyses
