Project Abstract
1: Monitor existing trial sites with improved NUE/SOM for microbial C, N, P cycling activities with a particular focus on bio-based fertilisers and/or processed wastewater. UL and Teagasc will monitor a field trial maintained by Teagasc as part of work package 1. 2: Develop a mechanistic understanding of plant-soil processes to minimise nutrient losses (leaching, atmospheric emission) and maximise NUE at greenhouse scale by modifying C, N, P stoichiometry, SOM, soil microbial biomass through soil carbon manipulation and bio-based fertilizer selection. Assessing microbial cycling of C, N, P contributing to NUE gains, crop yields and plant-microbe interactions. TU Munich will lead this objective with UL contributing to greenhouse experiments, the corresponding microbiome and soil stoichiometry analysis as well as data integration in work package 2. 3: Implement NUE maximisation solutions at field scale. Utilizing the findings from aim 1 and 2 in a field level demonstration for grassland and cropland (wheat). Monitor key processes identified in aims 1 and 2. U Warwick is leading this objective with UL contributing by setting up micro-plot trials with grassland for GHG emissions, grass performance and microbial immobilization & mineralization processes. 4: Dissemination and communication of findings from objectives 1-3. UL is leading this objective with all partners contributing. UL will lead the dissemination tot he academic community and support dissemination routes to agricultural advisors, fertiliser companies, biotech companies, policy makers, farmers and their advisors as well as the communication to the wider public.
