 「The hardness and component are different at a diggings area of akadama. the ingredients include, for example, the difference in content of the iron.


 It greatly divides it into a factor to control hardness, and there are two.


Firstly, dependent on the combination with oxide, and akadama which oxide has abundant becomes harder, but if there is too much oxide(example iron oxide), it adsorbs phosphoric acid, with that as a cause hindering the growth of plants.


The second, the hardness varies according to the way of the drying, that is to say a thing dried high temperature is more firm than a low temperature dried it, at the first stage.


Our akadama is firm by high temperature drying. but we do not make much of only hardness and keep it in mind to donate a thing of the quality suitable for the growth of the plants. 」
