Consequences of intraspecific and interspecific biodiversity in willows and poplars for community processes and ecosystem function (BiWaP); The Nutrient Network (NutNet). Soils are a significant reservoir of organic, fixed carbon worldwide. Humans have significantly increased the deposition of reactive, biologically available nitrogen; however, the effects of nitrogen enrichment on this significant carbon pool are poorly understood. I am investigating how nitrogen addition, and relevant intermediary drivers, influence the formation and turnover of soil organic matter in participatory sites of the Nutrient Network (NutNet), including the NutNet site at Cedar Creek. Identifying the mechanisms that drive soil organic matter cycling in response to nitrogen addition will inform future global soil carbon sequestration potential on our increasingly fertilized planet.
