Walkley-Black Method Soil Organic Matter Application and

The determination of soil organic carbon is based on the Walkley-Black chromic acid wet oxidation method. Oxidisable matter in the soil is oxidised by 1 N K 2Cr 2O 7 solution. The reaction is assisted by the heat generated when two volumes of H 2SO 4 are mixed with one volume of the dichromate. The remaining dichromate is titrated with ferrous sulphate. The titre is inversely related to the

The Walkley-Black (WB) method, because of its simplicity and rapidity, has been widely used during the past 50 years for determination of soil organic carbon (SOC), but one of the main problems with WB method in operation is determination of titration end point by the observer. In the past several years some studies have been done to reduce the human role in determination of titration end
