Human Alteration of the Phosphorus Cycle: Past, Present, and Future II
Session ID#: 8517
Session Description:
The phosphorus (P) cycle has supported biological productivity for eons through efficient recycling of P. In contrast, most fertilizer P used in global food production comes from mining, not renewable sources, and current human P use has many inefficiencies. The resulting imbalances of the global P cycle endanger food security, degrade water quality, and could be heightened by population growth, changing diets, and agricultural intensification. We solicit submissions that help understand the Anthropocene P cycle broadly, and its linkages to land use, climate, hydrology, coupled biogeochemical cycles, and management, through questions such as:
- How/why are human P fluxes, and P use, changing?
- How/why are fluvial P fluxes changing?
- How much legacy P has accumulated within the Earth’s critical zone, including agricultural soils, rivers, and lakes?
- What novel technologies and management practices reduce human P use, enable P recycling, and limit P loss from land to water?
