Conteúdo: 	The atmospheric concentration of nitrous oxide (N2O), an important greenhouse gas and natural catalyst of stratospheric ozone decay, is increasing, and agricultural soils are the main source of this increase. It is commonly recognized that mathematical models are needed to predict soil N2O emissions in light of the complex set of interacting factors regulating N2O emissions from soils. Existing models have not been widely tested in diverse agricultural systems. We compared soil N2O emissions predicted using a process based model, Denitrification-Decomposition (DNDC), with N2O emissions data collected between 2005 and 2007 from the long-term USDA-ARS Farming Systems Project (FSP) in Beltsville, Maryland.
