For using APSIM in sceanrio analysis and simulation of rice-based cropping systems, it is neccessary to model the C&N dynamics as the soil environment transitions between anaerobic (ponded) and aerobic (non-ponded) soil conditions.  Also included in this is additional C&N loss and gain mechanisms which come into consideration in long-term ponded water (such as algal growth, ammonia volatilisation etc).  This task requires the modification of SOILN and SURFACEOM to handle anaerobic conditions, and also the addition of a new module POND to simulate the new chemical processes occuring in rice ponds.
