  4. Assessment Methods for Soil Carbon

    Edited by John M. Kimble, Ronald F. Follett, Bobby A. Stewart

    Series: Advances in Soil Science

    Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement,...

  6. Soil Processes and the Carbon Cycle

    Edited by Rattan Lal, John M. Kimble, Ronald F. Follett, Bobby A. Stewart

    Series: Advances in Soil Science

    World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle...
