Need help to understanding the geologic setting and understanding of how Kanuma and Akadama soils used in bonsai are formed.
Are they found in areas other than the Kanuma City area? Are they formed from Mt Akagi deposits (Kanuma Pumice)… or some other origin? Are they waterlain or airfall pumice? Are they formed only in areas above or below ground water table?
What van you tell me about these soils in terms of genesis, distribution, etc?
