Abstract
Radiocarbon dating of charcoal and humin at different depths, of three soil pits in an oxisol, yielded similar age variations in relation to soil depth. This indicates that the charcoal and humin burial can be attributed to the soil fauna. Rates of accumulation in this soil range from 0.21 to 0.23 mm/year.
