摘要： Conversion of natural ecosystems (NE) to cropland significantly alters soil phosphorus (P) dynamics, influencing nutrient availability and crop yield productivity. Understanding these changes is essential for sustainable land management and optimizing agricultural outputs. This study investigates how natural ecosystem conversion affects soil P pools, while examining the role of fertilization in regulating P availability impacts on crop yield. A meta-analysis was conducted using data from diverse ecosystems and management scenarios to quantify changes in soil P dynamics and crop yield. Results showed that natural ecosystem conversion to croplands significantly raises soil available P (AvP) and total P (TP) levels, with grassland and shrubland conversions showing the highest increases: AvP by 37.8 % and 47.1 %, and TP by 22.3 % and 26.1 % for both. Fertilization significantly enhances soil P levels showing a significant response of 32.4 % for AvP and 30.2 % for TP, compared to reductions in non-fertilized soils. Acid phosphatase increases (+31.7 %) in non-fertilized soils but decreases (-7.87 %) with fertilization, while alkaline phosphatase decreases (-33.3 %) in fertilized soils and increases (+19.6 %) without fertilization. Microbial biomass P rises by 13.2 % with fertilization but declines by 9.21 % without it. Consistently, P fertilization significantly enhances crop yields with a moderate positive correlation observed between P addition rates. Non-fertilized conversions decrease AvP due to increased soil acidity and P fixation. Key environmental factors such as mean annual temperature (MAT) and mean annual precipitation (MAP) also influence P dynamics; notably, higher MAP is associated with greater total phosphorus (TP) accumulation. Overall, converting natural ecosystems to cropland, especially with P fertilization, significantly enhances soil phosphorus availability and crop yields, emphasizing the critical role of targeted P management in sustainable agriculture.
