The missing phosphorus legacy of the Anthropocene: quantifying residual phosphorus in the biosphere

A defining feature of the Anthropocene is the distortion of the biosphere phosphorus (P) cycle. A relatively sudden acceleration of input fluxes without a concomitant increase in output fluxes has led to net accumulation of P in the terrestrial-aquatic continuum. Over the past century, P has been mined from geological deposits to produce crop fertilizers. When P inputs are not fully removed with harvest of crop biomass, the remaining P accumulates in soils. This residual P is a uniquely anthropogenic pool of P, and its management is critical for agronomic and environmental sustainability. This dataset includes data for us to quantify residual P from different long-term managed systems. The following is the desccription of the dataset. There are 7 sheets in total. 1.

人类世的一个显著特征是对生物圈磷（P）循环的扭曲。输入通量的相对突然加速，而输出通量未相应增加，导致磷在陆地-水生连续体中净积累。在过去的一个世纪里，磷从地质沉积中被开采出来，用于生产作物肥料。当磷输入没有随着作物生物质的收获而被完全移除时，剩余的磷会积累在土壤中。这种残留磷是独特的、人为产生的磷池，其管理对于农业和环境的可持续性至关重要。本数据集包括数据，以便我们量化来自不同长期管理系统的残留磷。以下为数据集的描述。数据集共有7个工作表。1.
