Standard operating procedure for soil organic carbon.

Standard operating procedure for soil organic carbon.

3. Principle The 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 ...
