Outline of Final Research Achievements

The main objective of this study is to estimate the fate of nitrogen and water and heat transports in soils using numerical simulation and experiments. Surface energy balance model at vegetated soil surface was implemented in a simulation software for water, heat, and solute transport. A nitrogen and carbon transport model was also developed. In nitrogen transport experiment, nitrogen transform from NH4+ to NO2- and NO3-, NH4+ adsorption to a soil and NO3- transport was investigated. Root water uptake was also investigated in a soybean field experiment and pot experiment.
