Soil Science and Biogeochemistry
Globally, soils store at least twice as much organic carbon as circulates in the atmosphere, or is stored in the living biomass. But how does global change affect these biogeochemical cycles? As examples, will more frequent summer droughts and wildfires release more green house gases from the plant-soil system to the atmosphere and thus accelerate the warming? We test these questions in manipulative field and pot experiments combined with biogeochemical analysis.
