Abstract

In recent years there has been growing concern about the environmental impact of animal waste production. These excreta allows nitrogen losses to the atmosphere, either by evaporation or through the issuance of nitrous oxide, a potent greenhouse gas. This project has as objective quantify the emissions of N2O in the feces and urine of beef cattle on pasture and also losses in the form of N volatilized. The data will be used to refine the emission factors for N2O inventory and lifecycle analysis studies. (AU)
