Lower nitrous oxide emissions intensity from multi-species swards

Recent Teagasc research shows that multispecies grasslands can potentially reduce both nitrous oxide (N₂O) emissions and emissions intensities, and can contribute to more sustainable grassland production. Greenhouse gas measurements carried out by Saoirse Cummins showed that the annual greenhouse gas emissions per unit output (DM yield or biomass N) from the multi-species mixture were lower than those from perennial ryegrass receiving either 150 or 300 kg ha^-1 yr^-1 of inorganic nitrogen (N).

Webinar: piloting a biodiversity indicator in the Teagasc National Farm Survey

As part of the EU SmartAgriHubs project, Teagasc is investigating how to incorporate biodiversity into the Teagasc National Farm Survey. In a recent webinar, I presented the first results from the application of a habitat index to a sample of 300 farms in the NFS.
