Impact Summary

UK agriculture uses over 0.85 million tonnes of nitrogen (N) fertiliser each year which is spread over 8.2 million hectares of tilled and grassland soil. A major proportion of this added fertiliser, however, is not taken up by the crop and is lost to the wider environment. This results in a major economic loss to farmers and can lead to pollution of water courses, groundwater and the atmosphere. As the use of synthetic fertilisers will continue to be pivotal in food production for the foreseeable future, new ways are needed to effectively target the efficient use of this resource. One of the major outputs from our research programme will be the creation of new decision support tools that are based on on-farm, real-time soil data which continually update during the growing season. This represents a major advancement in current fertiliser guidance systems (e.g. RB209, Planet, Farmscoper). The outputs of our research on society can be grouped as follows: INDUSTRY: This research proposal is directly underpinned by key industry partners. These include (i) Yara UK who are one of the leading suppliers of N fertilisers, crop nutrient sensors (e.g. Yara-N-Sensor) and fertiliser guidance; (ii) Agricultural Industries Confederation (AIC) who are the agrisupply industry's leading trade association. AIC's Fertiliser Sector represents over 95% of the UK's agricultural fertiliser supply industry, worth about £2bn; (iii) British Grassland Society is a communication forum which through events and publications promotes the profitable and sustainable use of grass and forage; (iv) Agriculture and Horticulture Development Board (AHDB) is a Levy Board which represents the cattle, sheep, pigs, milk, potatoes, cereals, oilseeds and horticultural industries. AHDB are also responsible for reviewing current UK fertiliser recommendations associated with RB209. Our project directly aligns with the strategic priorities for all these industry organisations. All the main partners will be membersof our management board, and will provide invaluable guidance throughout the project and will facilitate the dissemination of the project findings. POLICY COMMUNITY: The results from this project will directly inform policymakers (e.g. Defra, DECC) by providing clear advice on future developments in precision agriculture including the environmental and economic costs and benefits and barriers to technology adoption. We will also provide guidance on the timelines and likely impact that adopting these technologies will have at the UK level and its potential impact on the UK N inventory. Policymakers are also central to our proposal (see WP5) ensuring dialogue throughout the programme. We will also build on our established links with Defra and Welsh Government to ensure effective dialogue. WIDER COMMUNITY: A web page and Twitter feed from the Bangor website will provide ongoing information on the project and its results. Different aspects of the project will be used for teaching, generating student projects, and will be presented at open days at (1) the Bangor University Agricultural Extension Farm, which is one of Defra's Sustainable Intensification Platform flagship sites, and (2) by our industrial partners. We will also feature the project in School Science Week, using visualisation of nitrogen pollution to stimulate wider discussion about agriculture and the environment. SCIENTIFIC COMMUNITY: Our research will inform scientists working in several areas of research (e.g. crop production, grazing management, water quality, greenhouse gas emissions and modelling). We will generate fundamental information on the use of in situ N sensors, plant-soil-microbial N cycling as well as providing new 3D mathematical modelling tools and information of the spatial heterogeneity of nutrients at a range of scales. These technologies will be promoted through the project-dedicated website, at national and international conferences and in journal publications.
