I made this biochar last weekend. I used up brush I got from a cedar tree that I needed to clear up.

Essentially this is a substitute for a burn pile. It took me a bit to figure out why it works as well as it does. I have two barrels that both look about the same that I did together.

I'll soak it in water for a while and try to activate it with something and chip it.

I also threw some old bovine bones in the dogs had brought up from somewhere.
