The focus of this research is to quantify and characterize soil carbon sequestration and stability in woody bioenergy plantation. Soil samples were collected from woody biomass plantation and adjacent agricultural crop and natural woodland ecosystems representing extremes of land use in the study region. The samples will be analyzed for soil parameters including  soil chemical properties (pH, CEC, BS, soil P, and C/N ratio) soil organic carbon concentrations, soil carbon fractions, and soil carbon size fraction. The expected results will not only contribute to the growing knowledge of ecosystem level benefits of biomass plantations but can also be used to model and simulate long-term environmental and economic benefits for the region and for scaling information to larger watersheds.
