The charge characteristics and physical properties of acid soils were compared with those of reference clays to elucidate the effect of the pedogenetic acidification process on soil physicochemical properties. The soil physics such as clay dispersibility and aggregate stability of the acid soils are considered to be ameliorated by acidification process, which is attributable to the increase in amorphous Al hydroxides and interlayering of 2:1 clays. This means that the pedogenetic acidification process plays an important role in maintaining a desirable soil structure in Japanese non-volcanic areas from the aspect of environmental conservation. The involved mechanism was discussed with special reference to the modification of charge characteristics of clays and binding agents between soil particles.
