| Outline of Final Research Achievements |
In order to predict the fate and transport of nitrogen and carbon in soils as a result of decomposition of soil organic matter (SOM), we modified the LEACHM SOM decay model to include plant root uptake, ion exchange, proton reactions, soil pH buffering, gas transport, and oxidation-reduction reactions for reduced paddy soils using the PHREEQC program. The modified SOM decay model was linked with HYDRUS-1D using the HP1 code. Furthermore, various saturated and unsaturated soil column experiments were conducted to monitor fate and transport of nitrogen with the SOM decomposition.
