Targeting N2O emission hot-spots in dairy pastures for mitigation action: microbes, stable isotope methods and modelling

Objective

Nitrogen (N) limits primary productivity in most terrestrial ecosystems, which has led to increased use of N fertilisers within farming systems. The amount of reactive N in global circulation has more than doubled; this has global significance as the N can cascade through different chemical forms in land, air and water, leading to a range of human health and environmental impacts. In order to achieve sustainable food production systems of the future, there is a need to improve knowledge on the best management of farm N, especially under increased demand for food production under a burgeoning human population. The Target-N2O project will deliver a high quality training-through research project aiming to improve N use efficiency and reduce emissions of the powerful greenhouse gas, N2O, from intensive dairy farms. The project will combine multi-disciplinary techniques in a novel way, including molecular ecology, stable isotope methods and whole-farm system modelling to determine the cost-benefits of an N loss mitigation strategy. The strategy would be to apply nitrification inhibitors to pasture areas which have been identified as farm-scale N2O emission hot-spots (e.g. areas of pasture around gateways, livestock shelter areas and camping areas). Such areas receive regular inputs of nutrients including labile N (through urine events) and carbon sources (via dung), which fuel microbial processes leading to enhanced and spatially variable GHG emissions. Evidence of the effectiveness of nitrification inhibitors to reduce N losses from these areas are lacking. The results of the action will have cross-sectoral impact (scientists, dairy and fertiliser industries and policy makers). The project will deliver decision support tools for farmers utilising such a mitigation strategy and will impact policy by improving national GHG inventories, establishing the effectiveness of cost-effective mitigation strategies.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
