Soil phosphorus (P) fractions are critical for understanding soil P dynamics and availability. This paper provides a global dataset of soil P fractions separated by the Hedley method. The dataset also includes key environmental factors associated with soil P dynamics and availability, including climate factors, vegetation, soil and parent material types, soil age, and soil physiochemical properties such as particle size, bulk density, pH in water, organic carbon, total nitrogen, and extractable iron and aluminium concentrations. This dataset includes measures of Hedley P fractions of 802 soil samples and was gathered through a literature survey of 99 published studies. Plant availability of each soil P fraction was noted. We anticipate that the global dataset will provide valuable information for studying soil P dynamics and availability, and it will be fused into earth system models to better predict how terrestrial ecosystems will respond to global environmental changes.
土壤磷（P）组分对于理解土壤 P 动态和有效性至关重要。本文提供了一个全球数据集，其中包含通过 Hedley 方法分离的土壤 P 组分。该数据集还包括与土壤 P 动态和有效性相关的关键环境因素，包括气候因素、植被、土壤和母质类型、土壤年龄以及土壤物理化学性质，如粒径、容重、水浸 pH 值、有机碳、总氮和可提取铁铝浓度。该数据集包含 802 个土壤样本的 Hedley P 组分测量值，是通过对 99 项已发表研究的文献调查收集的。还记录了每个土壤 P 组分的植物有效性。我们预计，全球数据集将为研究土壤 P 动态和有效性提供有价值的信息，并将其融合到地球系统模型中，以更好地预测陆地生态系统对全球环境变化的反应。
