As I understand it the ash becomes really rich soil in time....is that what the main soil there is? Volcanic in nature?
Thanks,

Yes, it is an excellent "fertiliser" in time and small doses. At first it is bad because it covers fields and blocks out sunlight but after the grass gets through the blanket it will grow better than ever. Fluorine or fluoride (not sure which is the correct word) comes with the ash and when consumed by livestock while grazing it dies.
