Summary
This multi-institutional field trial, conducted across the United Kingdom and Ireland, compared N₂O emissions from mono-species and multi-species grassland swards under intensive management. The findings suggest that increasing botanical diversity in intensively managed grasslands may offer a practical approach to mitigate N₂O emissions from livestock production systems, though the underlying mechanistic pathways remain incompletely characterised. The work addresses a significant climate mitigation challenge in intensive pastoral agriculture.
UK applicability
The study was conducted partly in the United Kingdom and is directly applicable to UK intensive grassland management and livestock production systems. The findings may inform mitigation strategies for UK pastoral farming under climate-related policy targets.
Key measures
N₂O emissions (nitrous oxide); sward botanical composition; intensity of grassland management
Outcomes reported
The study measured N₂O emissions from mono-species and multi-species grassland swards under intensive management across multiple field sites. The work assessed whether increased botanical diversity could reduce greenhouse gas emissions from intensively managed pastoral systems.
