Standard operating procedure for soil organic carbon ...
www.fao.orgThe determination of soil organic carbon is based on the Walkley & Black chromic acid wet oxidation method. Oxidizable organic carbon in the soil is oxidised by 0.167 M potassium dichromate (K 2 Cr 2 O 7) solution in concentrated sulfuric acid. The heat of reaction raises the temperature which is sufficient to induce substantial oxidation.
