Summary
This modelling study applied the DailyDayCent biogeochemical model to simulate nitrous oxide emissions from UK cropland and grassland systems, capturing both spatial heterogeneity and inter-annual variability. The work represents an attempt to improve predictive understanding of N₂O release from contrasting UK agricultural land uses across multiple institutions. Such spatially-explicit, temporally-resolved modelling approaches are relevant to estimating agricultural greenhouse gas inventories and informing emissions-reduction strategies in UK farming.
UK applicability
The study is directly applicable to UK agricultural conditions, having been parameterised with UK field data and representative of the range of soil types, climates and management practices found across UK cropland and grassland systems. The findings support evidence-based greenhouse gas inventory estimation and the design of regionally-tailored emissions mitigation strategies for UK agriculture.
Key measures
Nitrous oxide (N₂O) emissions (spatial and temporal variation); soil properties; management practices; climate variables
Outcomes reported
The study modelled spatial heterogeneity and inter-annual variability in N₂O emissions across UK cropland and grassland systems using the DailyDayCent biogeochemical model. Results characterised emissions patterns across contrasting agricultural land uses and soil–climate conditions representative of the UK.
