That's a very nice link, Nico, and an interesting subject. We have acid soils here, so ashes can be a plus but it's always a challenge to decide how much to apply, with a substance that can affect pH so dramatically. When I burned wood to heat my home, I mostly used the ashes in my compost, and let them contribute to that process. Since it rains a lot as time passes, the pH issues are resolved before the compost is ready to use.

One thing I learned, it is important to use very fine ashes from complete combustion, and avoid using coarse ash with bits of charred wood, which also contain creosote and can be toxic to plants.
