<div class="moz-cite-prefix">Dear readers,<br>
<br>
I am moving this topic from the Stoves Listserv to the basic
Biochar Listserv. Please place replies to the Biochar group.<br>
<br>
Erin, this is the first time I have heard such a statement
(below). <br>
<br>
Hugh McLaughlin has a strong preference for biochars that have
minimal tars and oils.<br>
<br>
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?<br>
<br>
Paul<br>

<p class="MsoNormal"><span style="color:windowtext">> </span>Other
issues: What about all those other tars and oils and vapors
that are combustible but for which there is not sufficient
Oxygen inside <span style="color:windowtext">> </span>the
biomass molecules? Are you expecting this to drain? Or
to remain inside the "char" that would be loaded with such
"gunk"? That <span style="color:windowtext">> </span>would
be interesting char for burning, but not as biochar for
soils and plants.<br>
<br>
<o:p></o:p></p>
</div>
<p class="MsoNormal"><span style="color:windowtext">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. <o:p></o:p></span></p>
