Abstract:
The Dc nitrification and Dc composition (DNDC) model was evaluated for its ability to etimate greenhouse gases emissions from agricultural land in Taiwan under various management practices and climate scenarios. Compared with actual observation data in paddy field, the results indicated that the model could estimate the CH4 and CO2 emissions satisfactorily. In addition, the sensitivity analysis of the soil texture, water management and climate scenarios could be used to understand the potential of greenhouse gases emissions. By incorporating necessary modifications based on the local soil properties and management practices, the DNDC model was proved to be an acceptable tool to estimate greenhouse gases emissions during the processes of agricultural production. Moreover, the DNDC model integrated with the spatial information from GIS databases could play an important role in evaluating the potential of greenhouse gas emissions from paddy fields in Taiwan.
