Fractionation of organic carbon based on susceptibility to oxidation

A new method is proposed for fractionation of soil organic carbon, based on its susceptibility to oxidation with KMnO4 solutions of various concentrations. This method can be used for: characterizing the organic matter of various soils, evaluation of qualitative changes of organic matter under the influence of fertilization and crop rotation, and for evaluation of susceptibility to oxidation of various substrates of humification
