Soil Carbon Turnover
The net carbon balance of forests is the small difference between very large fluxes of carbon uptake (via photosynthesis) and carbon loss (via respiration). If carbon uptake by forest vegetation exceeds C loss by vegetation and soils, the forest is a net sink of atmospheric carbon. Currently, regrowing temperate forest ecosystems of the eastern United States are storing C (Goulden et al. 1996; Greco and Baldocchi 1996; Hollinger et al. 1999; Curtis et al. 2002).
