Biomass sorghum production can affect the input of crop residue in quantity and quality and thus soil C sequestration and greenhouse gases emissions. However, such changes including soil C sequestration may take time to be monitored. Processed-based biogeochemistry models may be an option in predicting such long-term effects. In this study, we calibrated a biogeochemistry model, DayCent, using four-year biomass sorghum yield data and soil data and two-year greenhouse gases data. The long-term impacts of biomass sorghum production on soil C sequestration and GHG have been analyzed.
