TEAGASC is responsible for providing integrated research, advisory and training services for the agriculture and food industry in Ireland. Teagasc is a leading research institute in Ireland, undertaking innovative research in the areas of bioscience, agriculture production, food, the environment and the rural economy. The Moorepark Research Centre is one of the world's leading dairy research centres and specialises in pasture based systems of milk production. JohnstownCastle is Ireland’s leading research centre for soils and the rural environment. The centre has state-of-the-art laboratory facilities to support the research programme.
Teagasc provides a case study and site data on legume-based dairy production systems within Work Package 1. Measurements of soil fluxes of N2O and CH4 in both BFN and MFN systems and estimation of annual N2O budgets, studies of the contribution of N fixation to N2O emissions, and measures nitrate leaching from soil and dissolved N2O in soil water contribute to WP3. Historic and new datasets on legume-based pasture design and management are being provided (WP2, 4 and 6).
Teagasc contributes to the evaluation at the farm level of legume-based cropping practices and GHG mitigation potential (WP4); and is actively involved in knowledge interaction and research delivery (WP5).
