Dear readers,
I am moving this topic from the Stoves Listserv to the basic Biochar
Listserv. Please place replies to the Biochar group.
Erin, this is the first time I have heard such a statement (below).
Hugh McLaughlin has a strong preference for biochars that have minimal
tars and oils.
With many types of plants and soils and chars, there are sure to be
different results that can support either position. What evidence is
there, and what should be told to the novice users of biochar?

Actually, a lot of plants like the extra tars and vapors to be in the
char. Some of the most oily chars I've gotten a chance to test, have
been the ones that plants like. So it's good to widen the pool of
chars that we are looking at to include some of the other processes
that use the energy from the charmaking process to do useful things.
