Soil organic matter dynamics and the global carbon cycle

OSTI ID:10186393
The large size and potentially long residence time of the soil organic matter pool make it an important component of the global carbon cycle. Net terrestrial primary production of about 60 Pg C{center_dot}yr{sup -1} is, over a several-year period of time, balanced by an equivalent flux of litter production and subsequent decomposition of detritus and soil organic matter. We will review many of the major factors that influence soil organic matter dynamics that need to be explicitly considered in development of global estimates of carbon turnover in the world`s soils. We will also discuss current decomposition models that are general enough to be used to develop a representation of global soil organic matter dynamics.
