Times Cited Count：19 Percentile：65.81(Agronomy)A multi-layer atmosphere-SOiL-VEGetation model (SOLVEG) was modified to calculate the NH
exchange fluxes over a paddy field. The heat transfer at the paddy water layer and the dry deposition of water-soluble gases such as NH and SO
onto the wet canopy, as well as the emission potentials of NH from the rice foliage and the surface of floodwater or soil were incorporated into the model. The modified model reproduced the observed surface and NH fluxes, paddy water temperature, and soil temperature and moisture during both the fallow and cropping seasons. The "recaptured fraction" was defined as the ratio of the amount of volatilized NH recaptured by the foliage to the total amount. Numerical experiments using the modified model with varying emission potentials of NH showed that the recaptured fraction increased with an increase in the leaf area index (LAI) and saturated when LAI

In order to investigate the nitrogen cycling at the paddy field, a multi-layer atmosphere-soil-vegetation model (SOLVEG) was modified to simulate water and heat exchanges at the rice paddy field. The SOLVEG is useful to evaluate the impacts of atmospheric nitrogen deposition on paddy fields since the well-validated schemes of atmospheric gas and particle deposition onto leaf surfaces are included. The model was tested at the Mase paddy site in Japan. The SOLVEG reproduced well the temporal variations in of water, heat and momentum fluxes over the paddy field after harvest. The analyses of the calculated CO and surface fluxes were also made to clarify the atmosphere-rice plants exchanges during the growing season of rice plants.
