Consortium members at Michigan State University represent a well integrated group of internationally recognized researchers and extension leaders in a wide range of disciplines that include agricultural ecology, spatial analysis, agronomy, soil science, biogeochemistry, sociology and extension. Relevant expertise includes the measurement of greenhouse gas emissions and calculation of relative global climate forcing by soil emissions for agricultural, successional and forested systems. Related biogeochemical studies allow the measurement of subsurface carbon movement to geological horizons and to other landscape components such as lakes and streams. The role of plant growth, roots and soil physical parameters is investigated relative to expected cropping practices in future climate change scenarios. Soil organic matter investigations include the role of cations and nitrogen on carbon sequestration in agricultural and forested ecosystems. The spatial analysis and modeling group has excellent databases and expertise in investigating the role of weather, pests, and agricultural practices on crop production, soils and other ecological properties at the regional scale. The influence of human-societal controls on decision-making at farm, local, state and national scales are integrated into both the research and outreach activities of Consortium scientists.
