  • The challenge of modelling nitrogen management at the field scale: simulation and sensitivity analysis of N2O fluxes across nine experimental sites using DailyDayCent 

    Fitton N; Datta A; Hastings A; Kuhnert M; Topp CFE; Cloy JM; Rees RM; Cardenas LM; Williams JR; Smith K; Chadwick D; Smith P (2014)
    The United Kingdom currently reports nitrous oxide emissions from agriculture using the IPCC default Tier 1 methodology. However Tier 1 estimates have a large degree of uncertainty as they do not account for spatial ...
  • First 20 years of DNDC (DeNitrification DeComposition): model evolution 

    Gilhespy SL; Anthony S; Cardenas L; Chadwick D; del Prado A; Li C; Misselbrook T; Rees RM; Salas W; Sanz-Cobena A; Smith P; Tilston EL; Topp CFE; Vetter S; Yeluripati JB (2014)
    Mathematical models, such as the DNDC (DeNitrification DeComposition) model, are powerful tools that are increasingly being used to examine the potential impacts of management and climate change in agriculture. DNDC can ...
  • Global Research Alliance Modelling Platform (GRAMP): An open web platform for modelling greenhouse gas emissions from agro-ecosystems 

    Yeluripati JB; del Prado A; Sanz-Cobena A; Rees RM; Li C; Chadwick D; Tilston E; Topp CFE; Cardenas LM; Ingraham P; Gilhespy S; Anthony S; Vetter SH; Misselbrook T; Salas W; Smith P (2015)
    Carbon (C) and nitrogen (N) process-based models are important tools for estimating and reporting greenhouse gas emissions and changes in soil C stocks. There is a need for continuous evaluation, development and adaptation ...
  • Modelling spatial and inter-annual variations of nitrous oxide emissions from UK cropland and grasslands using DailyDayCent 

    Fitton N; Datta A; Cloy JM; Rees RM; Topp CFE; Bell MJ; Cardenas LM; Williams J; Smith K; Thorman R; Watson CJ; McGeough KL; Kuhnert M; Hastings A; Anthony S; Chadwick D; Smith P (2017)
    Agricultural soils are the primary source of nitrous oxide emissions due to management practices including fertiliser application. While fertiliser rates are one of the main drivers of nitrous oxide emissions, emissions ...
  • The potential for land sparing to offset greenhouse gas emissions from agriculture 

    Lamb A; Green R; Bateman I; Broadmeadow M; Bruce T; Burney J; Carey P; Chadwick D; Crane E; Field R; Goulding K; Griffiths H; Hastings A; Kasoar T; Kindred D; Phalan B; Pickett J; Smith P; Wall E; zu Ermgassen EKHJ; Balmford A (2016)
    Greenhouse gas emissions from global agriculture are increasing at around 1% per annum, yet substantial cuts in emissions are needed across all sectors. The challenge of reducing agricultural emissions is particularly ...
  • UK emissions of the greenhouse gas nitrous oxide 

    Skiba UM; Jones SK; Dragosits U; Drewer J; Fowler D; Rees RM; Pappa VA; Cardenas L; Chadwick D; Yamulki S; Manning AJ (2012)
    Signatories of the Kyoto Protocol are obliged to submit annual accounts of their anthropogenic greenhouse gas emissions, which include nitrous oxide (N2O). Emissions from the sectors industry (3.8 Gg), energy (14.4 Gg), ...
  • What agricultural practices are most likely to deliver "sustainable intensification" in the UK? 

    Dicks LV; Rose DC; Ang F; Aston S; Birch ANE; Boatman N; Bowles EL; Chadwick D; Dinsdale A; Durham S; Elliott J; Firbank L; Humphreys S; Jarvis P; Jones D; Kindred D; Knight SM; Lee MRF; Leifert C; Lobley M; Matthews K; Midmer A; Moore M; Morris C; Mortimer S; Murray TC; Norman K; Ramsden S; Roberts DJ; Smith LG; Soffe R; Stoate C; Taylor B; Tinker D; Topliff M; Wallace J; Williams P; Wilson P; Winter M; Sutherland WJ (2018)
    Sustainable intensification is a process by which agricultural productivity is enhanced whilst also creating environmental and social benefits. We aimed to identify practices likely to deliver sustainable intensification, ...
