The soil humus is composed of humic acid, fulvic acid and humin existing in the residue. Sodium pyrophosphate-sodium hydroxide extract is used to extract the humus. The extract has a very strong complexing ability, which can combine the insoluble humus in the water with the water and the water-soluble combined state to form the water-soluble Humic acid sodium salt, so that the humus is more completely extracted into the solution. Take a part of the leaching solution to determine the carbon content as the total amount of humic acid and fulvic acid.
