Two methods of organic carbon estimation were employed on three soil profiles (Caemarfon brick works, Lleiniog, & Penmon-buried profile; all belong to Salop series), formed on calcareous parent material, from North Wales, U.K. Lower recovery of "ADC was observed by ihe dichromate combustion method than from the loss-onignition (L.O.I.). However, the soils having greater clay and carbonate contents gave more %OC, at \ high temperature, by L.O.I. method. Although both the methods gave consistent results, the dichromate combustion method was more reliable and therefore suggested for calcareous and/or high clay soils.
