Dr. Davidson and his team’s research in biogeochemistry includes the exchange of plant nutrients from the land to streams and groundwater and the exchange of greenhouse gases between the soil and the atmosphere.

Areas of expertise include:

  • Biogeochemical effects of land-use change and land management
  • The global nitrogen cycle, including the global nitrous oxide budget
  • Soil microbial processes of nutrient cycling and greenhouse gas fluxes
  • Leaching of plant nutrients to streams and groundwater
  • Interdisciplinary studies of nitrogen management in agriculture
  • Interactions of C, N, P, and other nutrient cycles in terrestrial ecosystems
  • Land-water-atmosphere exchanges of greenhouse gases and nutrients
  • Temperature sensitivity of soil organic matter decomposition
  • Modeling soil microbial processes
