Abstract: The rapid development of large-scale livestock breeding and poultry raising industries in China has led to the emergence of a novel approach to the treatment of dairy farm waste - the use of dairy farm waste as organic fertilizer to farmland soil. However, the high phosphorus content of dairy farm waste may pose a risk of environmental contamination to farmland soil and groundwater. The study primarily focused on the alterations in the concentrations of various phosphorus forms in soil and the occurrences of soil phosphorus leaching and depletion. The results indicate that the SQ5075 field management mode exhibits the highest total phosphorus content, which is conducive to the improvement of soil fertility. In comparison to the background value, the phosphorus content under SQ5025 is observed to be lower. Consequently, it results in a continuous depletion of phosphorus, which is detrimental to soil improvement and crop cultivation. The total phosphorus content in soil solution under SQ5050 is the largest, which may increase the risk of soil phosphorus leaching.
