Technical Abstract: Nitrous oxide (N2O) is the largest greenhouse gas source from crop systems and quantifying it for the U.S. Greenhouse Gas Inventory is important. The objective of this study was to validate the ability of DAYCENT to simulate N2O emissions from bioenergy cropping systems. From weather, soil-texture class, and land-use inputs, DAYCENT simulates crop production, soil organic-matter changes, and trace-gas fluxes. Given the high variability on N2O fluxes in natural systems, DAYCENT captured the observed daily variability in N2O emissions and simulated the observed seasonal patterns within bioenergy crops and differences in annual mean emissions among systems reasonably well.
