The second hypothesis tested was the enhanced C allocation belowground will prime microbes for nutrient mineralisation via extracellular enzyme functions to meet enhanced nutrient demands.  The third hypothesis tested was that trees would take more nitrogen and that the order preference for different available nitrogen forms is amino acids, ammonium, and nitrate.\n\nCoupled with this hypothesis the experimental work included both field and laboratory characterisation of selected variables and their responses to CO2 enrichment including gross N mineralisation, litter decomposition, extracullular enzyme activities, mycorrhizal (arubuscular and ectomycorhizae) characterisation, hyphael turnover, root C and N exudation and root uptake rates and preferences. The data on these variables is provided in CSV files together with metadata files detailing the experimental, analytical and quality control aspects of the data collection, curation and finalisation.  These variables were assessed during the fourth to the sixth year of CO2 enrichment at BIFoR-FACE, thus creating a key data for the early responses of CO2 fumigation. Since BIFoR_FACE will continue the experiment into 2030s, thus this data provides the early responses in a long-term experiment of its kind in the UK and in northern temperate environments in the world.","distributionFormats":[{"name":"Comma-separated values (CSV)","type":"text/csv","version":"unknown"}],"distributorContacts":[{"organisationName":"NERC EDS Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"distributor","email":"info@eidc.ac.uk"}],"funding":[{"funderName":"Natural Environment Research Council","funderIdentifier":"https://ror.org/02b5d8509","awardNumber":"NE/T000449/1","orcid":false,"ror":true}],"id":"a05b9519-f0c8-48ef-a9c6-43d0326f590f","incomingCitationCount":0,"infoLinks":[{"url":"https://data-package.ceh.ac.uk/sd/a05b9519-f0c8-48ef-a9c6-43d0326f590f.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","type":"OTHER"}],"inspireThemes":[{"theme":"Environmental Monitoring Facilities","uri":"http://inspire.ec.europa.eu/theme/ef"}],"keywordsOther":[{"value":"Forest FACE"},{"value":"Elevated Atmospheric CO2"},{"value":"forests nutrient cycling"},{"value":"root exudation"},{"value":"root uptake preferences"},{"value":"forest soils enzyme functions"},{"value":"mature oaks"},{"value":"nitrogen mineralization","uri":"http://vocabs.lter-europe.net/EnvThes/20974"},{"value":"nutrient cycling","uri":"http://vocabs.lter-europe.net/EnvThes/20960"}],"keywordsTheme":[{"value":"Soil","uri":"http://onto.nerc.ac.uk/CEHMD/topic/17"},{"value":"Climate and climate change","uri":"http://onto.nerc.ac.uk/CEHMD/topic/4"}],"licences":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"}],"lineage":"The data was generated following the experimental set-up in 2020 at the BIFoR-FACE site.
