Technical Abstract: Nitrous oxide is the largest greenhouse gas source from crop systems. DAYCENT was used to compare N2O emissions from the following 3 bioenergy cropping systems: switchgrass, reed canarygrass, and a rotation of 3 yr corn, 1 yr soybeans, and 4 yr alfalfa. Although DAYCENT did not always capture the observed daily variability in N2O emissions, it did simulate the observed seasonal patterns within systems and differences in mean emissions among systems reasonably well.
