| 内容記述 | The DNDC model is a process-oriented simulation model of soil carbon and nitrogen biogeochemistry in agricultural ecosystem. It can simulate the emissions of various greenhouse gases and nitrate leaching from soils and its validity has been already tested and confirmed in North America, Europe and China. Andosols, which occupy 27% of cultivated land in Japan, is known to have very unique physical and chemical soil properties and it was uncertain whether the model could be used for the simulations with such unique soils. The model's validity for Andosols was, thus, tested based on the observed data and simulated results. The model seemed to simulate leached water accurately and leached nitrate reasonably well for the two experimental sites where only synthetic fertilizers were applied and composted cow manures were applied in addition to synthetic fertilizers as basal fertilization. There seemed to be problems related to leached nitrate prediction, however, and further developments and modifications of the model are necessary. The use of model simulations is useful in terms of determining more environmentally-sound farming system and several examples that can reduce the amounts of leached nitrate from cultivated lands are shown in this report. By altering the simulation scenarios and analyzing the simulation results, the most appropriate and effective measures in attempting to reduce nitrate leaching and greenhouse gas emissions from farm lands can be developed using the model. |
