| Research Abstract |
In order to predict the fate and transport of nitrogen in soils as a result of decomposition of organic matter, we implemented a coupled carbon and nitrogen cycling model based on the LEACHM code using the PHREEQC program. The carbon and nitrogen cycling model described with PHREEQC was linked with HYDRUS-1D using the HP1 code. Various nitrogen transport scenarios could be demonstrated for the application of organic matter to a variable-saturated soil under nonisothermal conditions. Furthermore, oxidation-reduction potential and dissolved oxygen were monitored in a ponded saturated paddy soil column to observe the formation of the surface oxidation layer and the reduced layer.
