In 1982 standard organic matter characterization studies on soil from a multicomponent archaeological site were conducted. Two simple laboratory procedures, the Ball Loss-on-Ignition and Walkley-Black wet oxidation, were used to characterize three hearth features containing charcoal. For surface organically enriched soil horizons (A, E, and plow zone) the two procedures generally yielded similar results. However, the results from these two procedures were not similar for the three sub plow-zone cultural features. Thus began a study of soils that has extended over twenty-five years, and involved over 7,000 samples from around the world in order to understand why subsoil anthropogenic organic carbon behaves differently from surface soil organic carbon.
