Phosphorus fixation in various soils was accelerated by: (i) the application of P in solution thus inducing its immediate dispersion in the soil, and (ii) increasing the rate of movement of the P in the soil by changes in the water regime. It was concluded that the dispersion of P in the fertilized soil volume is the rate-limiting step in the process of its fixation and thus P fixation could be described as a transfer-controlled process.
