土壤磷素组分是了解土壤磷素动态和有效性的关键。利用赫德利方法,建立了一个全球土壤磷组分数据集。该数据集还包括与土壤磷动态和可用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,土壤年龄和土壤理化性质,如粒度,容重,水中pH值,有机碳,总氮和可提取的铁和铝浓度。该数据集包括802个土壤样品的赫德利磷组分的测量,并通过对99项已发表研究的文献调查收集。植物有效性的每一个土壤磷组分。我们预计,全球数据集将提供有价值的信息,研究土壤磷的动态和可用性,它将被融合到地球系统模型,以更好地预测陆地生态系统将如何响应全球环境变化。
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.
