Summary
This review synthesises current understanding of nitrous oxide emissions from ruminant urine in intensively managed perennial pastures, examining both the underlying science and practical mitigation options. The paper, as suggested by its scope and publication in Current Opinion in Environmental Sustainability, addresses a significant source of agricultural greenhouse gas emissions and explores management strategies to reduce N₂O losses whilst maintaining productivity. The authors integrate soil science, animal management, and climate mitigation perspectives relevant to pastoral systems.
UK applicability
Highly applicable to UK dairy and livestock farming, where intensively managed perennial grasslands dominate pastoral production. Findings on N₂O mitigation from urine patches are directly relevant to UK climate policy targets and agricultural practice on grassland farms.
Key measures
Nitrous oxide emissions from urine; mitigation effectiveness; pasture management practices
Outcomes reported
The paper reviews science on nitrous oxide (N₂O) emissions from ruminant urine deposited on perennial pastures and examines mitigation strategies applicable to intensively managed grazing systems. It synthesises evidence on emission mechanisms and potential management interventions.
