Treatments (n = 4) were applied in the spring and autumn of 2016 and measurements were taken across a full year following application. The treatments in spring consisted of a control (no urine application), real sheep urine application (applied at an equivalent rate of 756 kg N ha-1) and artificial urine application (applied at an equivalent rate of 1066 kg N ha-1). In the autumn, the treatments consisted of a control (no urine application), real sheep urine application (applied at an equivalent rate of 1112 kg N ha-1) and artificial urine application (applied at an equivalent rate of 1004 kg N ha-1).\n\nSoil greenhouse gas (N2O, CO2 and CH4) fluxes were monitored from the experimental sheep urine patches for a full year (2016-2017). During the first nine weeks following treatment application, fluxes were monitored using a mobile automated greenhouse gas monitoring system (Queensland University of Technology, Institute for Future Environments, Brisbane, Australia) which samples from static chambers, analysing the samples for N2O and CH4 on a gas chromatograph (SRI 8610C, Torrance, USA) and CO2 fluxes on a LI-COR LI-820 (Licor, St Joseph, MI, USA). The system measures eight greenhouse gas flux measurements per chamber per day and is calibrated with certified reference gases to ensure accuracy. Subsequently, monthly manual greenhouse gas samples were taken from static chambers in the same plots to complete the year-round measurement of fluxes. Samples were analysed on a Perkin Elmer 580 gas chromatograph (Perkin Elmer Inc., Beverly, CT, USA), also calibrated with certified reference gases to ensure accuracy. The nature and units of the reported fluxes can be found in the supporting documentation associated with the fluxes. The N2O-N emission factors (% of N applied) were calculated from the N2O fluxes by calculating the cumulative emissions (area under the curve by trapezoidal integration) and expressing the proportion of applied urine-N emitted as N2O-N.\n\nIn addition to the greenhouse gas fluxes, the temporal dynamics of soil mineral N (NO3- and NH4+), total dissolved N, total dissolved organic C and gravimetric soil moisture are monitored throughout the study via soil sampling and analysis. Above ground biomass harvests were taken periodically and the foliar N content and C-to-N ratio determined. Supporting meteorological data are provided in addition to characterisation of the soil properties at each study site. Full details of methods and quality control procedures are provided in the supporting documentation associated with each deposited data file.","metadataDate":"2026-07-24T18:54:20","notGEMINI":false,"onlineResources":[{"url":"https://data-package.ceh.ac.uk/data/0434c74c-4a8e-45b8-a187-13e422c0ed0f","name":"Download the data","description":"Download a copy of this data","function":"download","eidcDistribution":true,"type":"OTHER"},{"url":"https://data-package.ceh.ac.uk/sd/0434c74c-4a8e-45b8-a187-13e422c0ed0f.zip","name":"Supporting information","description":"Supporting information available to assist in re-use of this dataset","function":"information","eidcDistribution":false,"type":"OTHER"}],"publicationDate":"2020-02-03T00:00:00.000Z","publishers":[{"organisationName":"NERC Environmental Information Data Centre","organisationIdentifier":"https://ror.org/04xw4m193","role":"publisher","email":"info@eidc.ac.uk"}],"relAll":[{"title":"Nitrous oxide emissions from livestock urine in upland grasslands in North Wales, UK","publicationStatus":"published","href":"https://catalogue.ceh.ac.uk/id/ba449aa4-51cd-4bee-9c4b-9747b70e0894","rel":"http://purl.org/dc/terms/isPartOf","associationType":"aggregate"}],"relPartOf":[{"title":"Nitrous oxide emissions from livestock urine in upland grasslands in North Wales, UK","publicationStatus":"published","availability":"Unknown","href":"https://catalogue.ceh.ac.uk/id/ba449aa4-51cd-4bee-9c4b-9747b70e0894","rel":"http://purl.org/dc/terms/isPartOf","associationType":"aggregate","geometry":"POLYGON((-4.308 52.446, -4.308 53.303, -3.006 53.303, -3.006 52.446, -4.308 52.446))"}],"relationships":[{"relation":"http://purl.org/dc/terms/isPartOf","target":"ba449aa4-51cd-4bee-9c4b-9747b70e0894"}],"resourceIdentifiers":[{"code":"https://catalogue.ceh.ac.uk/id/0434c74c-4a8e-45b8-a187-13e422c0ed0f"},{"code":"10.5285/0434c74c-4a8e-45b8-a187-13e422c0ed0f","codeSpace":"doi"}],"resourceType":{"value":"dataset"},"rightsHolders":[{"organisationName":"Bangor University","organisationIdentifier":"https://ror.org/006jb1a24","role":"rightsHolder"}],"spatialReferenceSystems":[{"code":"http://www.opengis.net/def/crs/EPSG/0/27700","title":"OSGB 1936 / British National Grid"}],"spatialRepresentationTypes":["textTable"],"spatialResolutions":[{"distance":"100000","uom":"urn:ogc:def:uom:EPSG::9001"}],"temporalExtents":[{"begin":"2016-03-01","end":"2017-10-01"}],"title":"Sheep urine patch greenhouse gas emissions from a semi-improved upland grassland in North Wales, UK","topicCategories":[{"value":"biota","uri":"http://inspire.ec.europa.eu/metadata-codelist/TopicCategory/biota"}],"topics":["http://onto.nerc.ac.uk/CEHMD/topic/17","http://onto.nerc.ac.uk/CEHMD/topic/4"],"type":"dataset","uri":"https://catalogue.ceh.ac.uk/id/0434c74c-4a8e-45b8-a187-13e422c0ed0f","useConstraints":[{"value":"This resource is available under the terms of the Open Government Licence","code":"license","uri":"https://eidc.ac.uk/licences/ogl/plain"},{"value":"© Bangor University ","code":"copyright"}]}
