Overestimates of black carbon in soils and sediments

  title={Overestimates of black carbon in soils and sediments},
  author={Myrna J. Simpson and P. Hatcher},
Several recent reports suggest that black carbon (BC), which broadly encompasses charcoal, soot, and other forms of pyrogenic carbon, may constitute a significant proportion of the refractory carbon in soil and sedimentary organic matter. BC is a sink for biospheric and atmospheric carbon dioxide, and is intimately tied to the biogeochemical cycling of both carbon and oxygen through its role in organic matter cycling. Additionally, BC may represent a large fraction of the “missing carbon sink… CONTINUE READING
