Re: DIY Biochar
Ok, sound s like a lot of you have a very good understanding of this topic. I am curious what yor thoughts on this question might be.
I do make my own charcoal in 2 different ways. I have a top down updraft burner I made out of a couple of 55 gallon drums which I will fire up 2 times a year or so using wood chips, branches, small tree trunks, etc. and I also have a regular burn pit into which I throw most other things that don't go into the compost.
With the burn pile I of course get a lot of ash but also a lot of what looks like charcoal. With the tdud burner it's of course all charcoal, very little ash.
My question is this: is there a significant difference between the 'charcoal' from the burn pile and the tdud burner?
