There's a kid in the community who brings me a combination of good stuff for my garden, including spent ash, goat manure, coconut hulls, and charcoal powder.
On initial observation, the charcoal powder is quite dark (unless mixed with our pale local clay), while the spent ash is more . . . Ashy. Fresh ash will be white, but it leaches the white color quickly and leaves behind a dark gray color.
But my question is the makeup. I understand that fresh wood ash consists of a large amount of potassium, and that the potassium leaches out when it rains. So what's left? Is it a form of biochar that's left over? How does spent ash differ from biochar (and from fresh ash), and how can it benefit (or not) the soil?

We noticed he had no friends. So we gave him this tiny ad:
