No, it hasn't, but I expect it's of little consequence. The idea of using charcoal as a nutrient buffer is an obvious one, and I'm a little surprised more hasn't been made of it historically. Of course burning slag in fields has been part of ag practice for centuries and it was certainly known in all cultures to be beneficial to soil. I'm trying a couple of different types of mix and match of about a 1lb per square foot for starts in the Uala, which is genetically identical and should provide sensibly good indications, at least, satisfactory to myself.
The guava, again, makes near perfect charcoal.
