Belowground Responses to Rising Atmospheric CO₂ Implications for Plants, Soil Biota and Ecosystem Processes

About this book

As atmospheric CO₂ increases, there will almost certainly be alterations in soil carbon fluxes, accompanied by changes in the partitioning of carbon between organic structures and to soil processes, which have the potential for further altering the structure and function of terrestrial ecosystems.
