By using the 32P isotopic tracer method, experiments have been conducted to investigate phosphorus transport in three different forms of four types of soils in Shaanxi Province.It is found that: (1) Phosphorus can hardly break through the soil column in experiment, as the retardation factor,R, is larger than 1 in most cases, particularly in soils rich in clays and calcium carbonate.After eliminating CaCO3 from the soil, the value of R will decrease.(2) While rising temperature makes the value of R increase and the value of diffusion-dispersion coefficient, D, decrease; and (3) It is viable to use the CXTFTT program for calculation of phosphorus transport parameters.
