EFEM-DNDC is a GIS-coupled economic-ecosystem model, which simulates greenhouse gas (GHG) emissions from typical livestock and crop production systems in Baden-Württemberg, Germany. The model is a coupling of the EFEM model (Angenendt, 2003) of economic farm production (simulates crop and… Read more ...
Many forest management practices are believed to enhance carbon mitigation, such as the restoration of forested wetlands however there is a lack of long-term field studies.
Forest-DNDC model which runs on a daily time-step, links forest and soil processes and was developed to… Read more ...
A national inventory of nitrous oxide emissions from cropland in China was developed by integration of the DNDC model (version 8.3P) with county scale data on soil properties, climate, nitrogen fertiliser use and livestock numbers - from which to derive manure nitrogen inputs - and agricultural… 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… Read more ...
NZ-DNDC is a modified version of DNDC that includes a number of alterations to best reflect the conditions found in New Zealand and was developed by a team at Landcare Research in New Zealand. The presence of distinctive and diverse soil types within a short distance and soils having a higher… Read more ...
A decision support system for quantifying impacts of management alternatives on greenhouse gas emissions from agro-ecosystems in the U.S.
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… Read more ...
A number of studies adapt the DNDC model for use on rice paddy systems.
The DNDC model was adapted to better simulate greenhouse gas emissions from rice paddy ecosystems by Li et al. (2004). Modifications included simulation of anaerobic biogeochemistry and rice growth and… Read more ...
LandscapeDNDC is partly based on the DNDC model and contains a series of new features "with regard to process descriptions, model structure and data I/O functionality." (Haas et al., 2012). LandscapeDNDC incorporates functions of DNDC, PnET-N-DNDC/Forest-DNDC and was further developed from… Read more ...
The integrated DNDC-Europe model was developed to assess the affect of agri-environmental policy on greenhouse gas (GHG) emissions. The large scale economic model for agriculture, CAPRI (Common Agricultural Policy Regional Impact Assessment) detailed in Britz (2005), was integrated with the… Read more ...
UK-DNDC is a modification of DNDC, the process based model of carbon and nitrogen biogeochemistry in agro-ecosystems, designed specifically for application in the UK. This involved the addition of UK-specific input data to the DNDC database and simulation of daily C and N inputs from… Read more ...
Manure-DNDC is a process based model which describes manure organic matter turnover and gas emissions, where the relations between environmental factors and reactions such as decomposition, hydrolysis, nitrification, volatilisation etc are incorporated in a computable framework in order to… 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 ...
Grote et al. (2011) integrated dimensional tree growth and mortality routines with MoBiLE-PSIM, a physiologically based process model, to enable quantification of the impacts of direct and indriect impacts of forest management on carbon balances within ecosystems.
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 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… Read more ...
Estimate Carbon in Organic Soils –Sequestration and Emissions (ECOSSE):
Whilst a few models have been developed to describe deep peat formation and turnover (for example Clymo 1992), until recently, none had been developed that were suitable for examining the impacts of land use and… Read more ...
Crop-DNDC is a process-orientated, agroecosystem model that integrated detailed crop growth algorithms with the DNDC soil biogeochemical model to better simulate carbon, nitrogen and water cycles. Crop-DNDC was developed at the Canada Center for Remote Sensing, Ottawa, and simulates crop… Read more ...
PnET-DNDC is a process based model that integrates three existing models (PnET, DNDC and a nitrification model) with several additional features. PnET is a forest physiology model that predicts photosynthesis, respiration, organic carbon production and allocation and litter production for… Read more ...
SUNDIAL is a dynamic computer model of nitrogen turnover in the crop/soil system. It incorporates current scientific knowledge on the individual processes of nitrogen turnover and integrates these processes to simulate what happens in the whole soil. SUNDIAL requires readily… Read more ...
RothC is a model for the turnover of organic carbon in non-waterlogged topsoil that allows for the effects of soil type, temperature, soil moisture and plant cover on the turnover process. It uses a monthly time step to calculate total organic carbon (t ha-1), microbial biomass carbon (t ha-1)… Read more ...
The PnET-N-DNDC process-orientated model which simulates C and N dynamics in upland forest ecosystems and the FLATWOODS (Sun et al., 1998) distributed hydrological model have been integrated to create the Wetland-DNDC model. The main structure of Wetland-DNDC is taken from PnET-N-DNDC (Li… Read more ...
DNDC (DeNitrification-DeComposition) is a process based model of carbon and nitrogen biogeochemistry in agro-ecosystems.
