Two soil colloidal components i. e, fine clay （〈0. 2 μm） and coarse clay （0. 2-2. 0μm） were separated by centrifugation. Two treatments applied to fine and coarse clays were organic matter left on the samples （organic clays） and organic matter removed from the samples by H2O2 （inorganic clays）. Brown soil was divided into four types of clays： coarse organic clay （0. 2-2.0 μm, organo-mineral complexes）,
