| Outline of Final Research Achievements |
The main objective of this study is to estimate the fate of nitrogen and water movement in a crop field using numerical simulation. Field and pot experiments with soybeans were conducted to obtain a ratio of transpiration and evapotranspiration, and a water stress response function of soybeans. A numerical simulation using the HYDRUS-1D code was conducted with these parameters, and water movement with evapotranspiration and nitrogen transport with root uptake in a root zone were evaluated.
