{"access":"N14CP is open access: available to use at no cost by request to the model owner.","capabilities":"N14CP is a process model based on observations and understanding of how soil behaves in response to changing land management and nitrogen inputs.  It predicts effects on the development of soil organic matter and nutrient solute fluxes (nitrogen, carbon and phosporus: NCP) in ecosystems (including arable agriculture, forest and peatland).  It works at large spatial scales (wholes UK on a 5km grid) and long timescales over which organic matter develops (decades to centuries).  N14CP provides the core soil module for a family of other UKCEH models including LTLS, MADOC, IDMM and CAMPS (see separate entries).","description":"N14CP predicts the effects of land management and nitrogen deposition (from air pollution) on soils, specifically: the long-term development of soil organic matter; and fluxes of nitrogen, carbon, and phosphorus nutrients through soil.  It is used by researchers to analyse long-term, large scale impacts of land use change, air pollution and agricultural practices on soil carbon and greenhouse gas emissions.  N14CP also provides the core soil module for other UKCEH models (see Capabilities).","fundingSources":"Early development of N14CP was funded by Defra and the UKRI-NERC Macronutrient Cycles programme.","id":"281d59ca-cad4-4e75-a886-3cd8f7b585b3","infrastructureCategory":{"value":"models","description":"Environmental models","infrastructureClass":"Digital infrastructures","uri":"http://vocabs.ceh.ac.uk/ri/model"},"infrastructureChallenge":[{"value":"Pollution"},{"value":"Climate change: mitigation"}],"lifecycle":"Development of N14CP started in 2009, using Defra Air Quality funding, and the first version was published as N14C in 2014.  The phosphorus cycle was added under the NERC Macronutrient Cycles programme and published as N14CP in 2016.  A third version with agricultural flows was initiated to model an Indian catchment for a Newton-Bhaba project, finalised under an EPSRC-LWEC fellowship, and published as N14CPag in 2020.  Applications of the model continue, with investment to date totalling approx 15 person-years.","metadataDate":"2025-04-09T09:24:47","onlineResources":[{"url":"https://bitbucket.org/vjanes/n14cpagri-site/src/master/","function":"website","type":"OTHER"},{"url":"https://eidc.ceh.ac.uk/images/browsegraphics/n14cp.png","function":"image","type":"OTHER"}],"owners":[{"displayName":"Ed Rowe","organisationName":"UK Centre for Ecology & Hydrology","organisationIdentifier":"https://ror.org/00pggkr55","role":"owner","email":"enquiries@ceh.ac.uk","fullName":"Ed Rowe"}],"partners":"N14CP was developed by UKCEH.

It focuses on soil organic matter production and cycling, in contrast to land-surface models such as JULES/TRIFFID which are primarily based on leaf-scale physiology.  N14CP's relatively coarse timestep (seasonal, i.e. 1/4 yearly) requires only seasonal data input, and allows runs that cover the timescale over which soil organic matter develops (decades to millenia).  N14CP is thus uniquely suited to simulating changes in land use and carbon stock for a wide range of ecosystems (such as arable, forest and peatlands).","uri":"https://catalogue.ceh.ac.uk/id/281d59ca-cad4-4e75-a886-3cd8f7b585b3","users":["N14CP is used by UKCEH with Defra and wider researchers."]}
