Abstract:The conversion of wetland to cropland is believed to induce soil organic carbon(SOC)loss. To simulate the changes in SOC due to
marshland conversion, an existing model(Soil:C)was modified in this paper. Soil:C was originally developed to simulate SOC dynamics in
cropland, in which SOC was simply viewed as a mono:component. Modification to the original model was made by splitting SOC pool into two
