Effect of Freeze-Thaw Action on Phosphorus Adsorption and Desorption in Forest Wetland Soils at High Latitudes

Abstract:

To clear the effect of freezing and thawing on the soil phosphorus adsorption and desorption of northeast China high latitude forest wetland, the change of soil phosphorus elements after five complete freeze-thaw cycles was analyzed with Wuyiling National Wetland as experimental subjects. Result shows that the soil phosphates desorption increased after influenced by five complete freezing and thawing. Soil sample which initial phosphates concentration is 40、80、240 mg/L reached minimum value after three freeze-thaw cycle and then increased. Compared to the without freeze-thaw soil, phosphorus adsorption capacity of different initial concentrations of phosphate solution samples was increased after five freeze-thaw cycles indicating that freeze-thaw cycle has obvious effect on soil phosphorus adsorption and desorption.
