Unravelling the Biogeochemical Cycles of Carbon and Nutrients in Forest Ecosystems:Innovative Approaches with Advanced Stable Isotope and NMR Techniques as well as Soil Chemical and Physical Methods
Long-term impacts of global climate change (GCC) and local forest management on important biogeochemical cycles of carbon (C) and nutrient cycling in the soil-plant ecosystems are complex and difficult to assess, particularly under gradually and continuously rising atmospheric carbon dixoide concentration CO2 and warming in the real world with multiple limiting factors. In this presentation, we highlight the recent developments and applications of advanced stable isotope, nuclear magnetic resonance (NMR) and bio-molecular techniques, in an integrated approach with innovative rhizosphere and tree ring methods, for improving our understanding and management of above- and below-ground C and nutrient cycling processes in forest ecosystems, particularly in response to GCC and local management practices as well as mitigation/adaptation strategies. The opportunities and limitations of these techniques for investigating C and nutrient cycling processes in forest ecosystems are discussed, in the context of both short- and long-term impacts on the above- and belowground processes. Improved understanding and knowledge of environmental fingerprints of the biogeochemical cycles embedded in tree rings can be effectively used to account for long-term forest productivity and C stocks at local, regional and global scale in response to the future GCC and management options.
