Cropping systems can have a tremendous effect on the greenhouse gas emissions from soils. The objectives of this study were to compare greenhouse gas emissions from traditional (continuous corn or corn/soybean rotation) and biomass (miscanthus, sorghum, switchgrass) cropping systems. Biomass cropping systems were initiated in 2008, and thus, greenhouse gas emissions have been monitored throughout the growing season for four years. In this presentation, we will present the results of CO2, CH4 and N2O emissions from soils on a crop rotation basis to compare the sustainability of the various systems.
