Abstract: Modelling approaches have already been used to quantitatively assess the trade-offs between crop yield and N2O emissions as impacted by management practices. However, the model's performance in terms of predicting N2O emissions was mainly assessed against total emissions per growing season or year, which may reduce accuracy in modelling due to the uncertainties in total emissions estimated using the manual (static) chamber method.
