Mr. Elder, I would think that the wood ash could be a good amendment for the calcium and other trace elements. Just be careful that you don't go overboard, as eggshell, aragonite, wood ash, and calcium carbonite can all raise PH. I never considered carbon as an additive. I have always used carbon in the ABG mix I use to help keep the soil smelling fresh and also for better drainage. I don't foresee any problems with using some carbon/charcoal between the clay particles.
Questions are not ignorance. Questions are the birth of knowledge.
