Summary
This field-based study evaluated the potential for increasing plant species diversity in intensively managed grassland swards to mitigate nitrous oxide emissions, a potent greenhouse gas associated with livestock production. As suggested by the research design and authorship, the work examined whether multi-species grassland mixtures could reduce N₂O flux without compromising agronomic productivity. The findings indicate that botanical diversity may offer a practical agronomic pathway to lower emissions intensity in conventional grassland management systems used in livestock farming.
UK applicability
This work is highly applicable to United Kingdom grassland and livestock systems, given the shared intensity of dairy and beef production on managed swards and comparable soil and climate conditions. The findings could inform grassland management recommendations and agri-environment schemes targeting emissions reduction in UK pastoral farming.
Key measures
Nitrous oxide (N₂O) emissions flux; plant species richness and composition; grassland productivity; soil and management variables in intensive grazing systems
Outcomes reported
The study measured nitrous oxide emissions from intensively managed grassland swards varying in plant species composition. The research assessed whether multi-species mixtures could reduce N₂O flux whilst maintaining or sustaining productivity in livestock grazing systems.
