Re: DIY Biochar
I burn my yard debris and get a lot of charcoal if I rake the burning embers around instead of letting them cook down to ash. I mix that in with dirt and sawdust for excellent tree and shrub mix.
Charcoal briquettes have coal dust in them as well, which is why you get that sulfurous odor while its burning. IDK if that will affect the results or not if you were to use it. Seems to me as though it would tend to drop the pH significantly though.
