Short summary
The magnitude of N2O emissions from managed grasslands depends on weather and on harvesting and fertilizer practices. Modelling provides a means to predict these emissions under diverse weather and management types. In this modelling study, we show that N2O emissions depend on how weather affects temperatures and water contents of surface litter and near-surface soil. N2O emissions modelled from the grassland were increased by suboptimal harvesting practices, fertilizer timing and soil properties.
