Here is a short Bio-Char video I found on youtube. It is interesting but not particularly informative in any way that may be useful. Two things in the video that I should point out. 1. It really seems that people are having a hard time realizing that char in and of itself is not at all a fertilizer, that fertilizer has to be applied to the ground or to the char so that the char can absorb and slow release it. 2. One of the speakers mentions something about growing bio-mass in order to make bio-char, I completely disagree with this idea in every way possible, it is akin to growing and using land that could be used for food production for bio-fuels. Now if you want to use agricultural residue, that is fine, but growing bio-mass just for bio-char seems to defeat the purpose in my opinion. Sometimes folks have to realize that they can't have their cake and eat it too.
