Current Projects

Farm Sustainability Tools for Efficient Nutrient management (FaSTEN) will develop new knowledge to improve nutrient use efficiency on farms thus reducing potential N losses and emissions to the environment. FaSTEN will build new understanding of soils and key technologies for efficient nutrient management and will identify best knowledge transfer methods for these primary stakeholders. Nutrient management support tools tailored to specific soils, environments and farming systems will be developed to aid farmers and advisory personnel to make profitable and sustainable nutrient management decisions and to benchmark future success. The overall goals of FaSTEN are to develop a decision support tool and nutrient management technologies which harness a new understanding of plant-soil-biodiversity interactions driving nutrient dynamics to deliver soil specific nutrient advice for grassland & arable farms in Ireland. FaSTEN will directly support Food Wise 2025 goals to enhance the sustainability of primary food production systems and will help benchmark nutrient use and environmental standards on farms.  This project is being conducted in partnership with University College Dublin & Waterford Institute of Technology
