Bug Friendly Biochar
Nikolaus Foidl, September, 2009
Some Photos which prove that normal 450 degree Saligna char for barbequu use is quite bug friendly, housing demand for three different bugs is high and the bugs are still alive after digging through and forming there pupae. So high toxicity of the volatiles or the char it self seems to be an issue to overcome by some bugs. ( or its an other urban myth to be busted?) If a swiss cheese would look like this the would advertise him as an aerogel.
Please add the photos to your collection in the bio char list.
With my best regards Nikolaus
