390 Symposium--Changes In Soil Carbon Due to Climate and Human Activities

Oral Session

Soils currently represent the largest global carbon pool in terrestrial ecosystems; however some of these reserves could be lost to the atmosphere because of human activity and climate change. Human activities affect the stability of soil carbon stocks directly (land use change) and indirectly through species change, climate, or atmospheric-N deposition. This session invites papers that examine the past, current and future status of soil carbon stocks in the context of change brought about by human activity and changing climate. Papers that examine these processes over larger regions using modeling and remote sensing as well as smaller plot-to-watershed scale studies are encouraged to join our special session.
