    Kröbel et al. (2011) found that DNDC (version 9.3) overpredicted the growth of above ground biomass and nitrogen during the first half of the growing season, when assessed using experimental data from Swift Current (Saskatchewan) and St-Blaise (Quebec).  Kröbel et al. (2011) therefore introduced… Read more ...

    A regional framework for calculating nitrous oxide emissions from intensive agricultural land was developed by integration of the DNDC model (version 8.3P) with regional data on soil and climate, land use and farm practices for Belgium (Beheydt, 2006). The regional predictions of nitrous oxide… Read more ...

    Nest-DNDC is an integration of Northern Ecosyste Soil Temperature (NEST) model and DNDC that upscales methane fluxes from plant communities to ecosystem scale in permafrost peatlands.  Information is exchanged between the two models at code level, so the model is able to simulate the interaction… Read more ...

  • DNDC-CSW
    February 2022

    A Canadian version of DNDC (DNDC v.CAN) was developed to simulate biogeochemical cycling in agro-ecosystems under cool climatic conditions and management representative of Canada. This model should also be applicable for other temperate regions. It was first denoted as DNDC-CSW as conceived by… Read more ...

  • PnET-N-DNDC
    February 2022

    PnET-N-DNDC was modified by Kiese et al. (2005) to produce reliable estimates of N2O emissions from tropical rainforest ecosystems, a significant source of global N2O.  Differences in forest growth and soil hydrological properties between temperate and tropical regions meant the model required… Read more ...
