AbstractFreeze-thaw cycles (FTCs) can strongly influence the physical and chemical properties of soils in cold regions, which can in turn affect the adsorption-desorption characteristics of phosphorus (P) in the soil. In this study, a series of one-dimensional laboratory freeze-thaw experiments were conducted to determine the adsorption-desorption behavior of P in soil. Results showed that greater numbers of FTCs were associated with a decrease in the adsorption capacity of P in soil. Langmuir and Freundlich equations were adopted to fit the isothermal adsorption curves of P in soil. Values of the critical fitting constant indicated that FTCs weakened the absorption capacity of P in soil. At identical concentrations of exogenous P, the P desorption ratio for soil samples treated with FTCs was greater compared with the ratio measured in untreated soil.
