Appendix dataset for "Differential responses of soil phosphorus fractions to nitrogen and phosphorus fertilization: A global meta-analysis"

Here, we conducted a global meta-analysis based on 818 observations of soil P fractions from 99 field N and P addition experiments in forest, grassland, and cropland ecosystems ranging from temperate to tropical zones. In the dataset, two commonly used P fraction extraction methods were employed: the Chang and Jackson inorganic P (Pi) and the Hedley P extraction methods.
