<DIV>I make some top notch smoked salmon, and know what it takes to make people
say “wow! that is really good”. the funny thing is that what it takes to
properly smoke salmon is pretty much exactly what a guy tries to avoid with the
gasifier a cold tar laiden smoke. Is this harmful to your health????
it doesn’t matter as it tastes good enough “to die for”, it just makes me
wonder, have our genetics been time altered (somewhat like the signaling network
of the trees you talk of) to be predisposed to enjoy the taste of something
cooked over a “cold/smoky fire”?</DIV>

<P style="MARGIN-TOP: 4pt" class=MsoPlainText>Jeff and...<o:p></o:p></P>
<P style="MARGIN-TOP: 4pt" class=MsoPlainText>There's a lot of different
opinions on the value/harm of the "tars" in the soil. My instinct says "no-no!"
but some people drink the distillate and think that it is God's
blessing!<o:p></o:p></P>
<P style="MARGIN-TOP: 4pt" class=MsoPlainText>If we observe natural phenomena,
for instance forest burns (which, presumably, have multiple regimens of
combustion, from hardly-at-all to pure ash) we see that there is usually a
strong recovery after a burn, but the ecosystems are usually not replaced,
intact, but forced to begin their long, progressive cycle once
again.<o:p></o:p></P>
<P style="MARGIN-TOP: 4pt" class=MsoPlainText>A study of 19th-century charcoal
kilns in the Eastern U.S., show that there is a lasting effect on the sites on
which they were located. On the other hand, many suggest that the aromatic
compounds produced during pyrolytic combustion are valuable components of the
signaling network that tells seeds and the soil ecosystem that the sky has
opened and that the system has an altered competitive structure.<o:p></o:p></P>
<P style="MARGIN-TOP: 4pt" class=MsoPlainText>Maybe a little is good; and a lot
is bad. But despite the evidence that many of the polyaromatic hydrocarbons
remaining in the char produced for biochar applications is carcinogenic, some
certifying bodies have declared it "Organic" and suitable for unrestricted use
in agricultural applications.<o:p></o:p></P>
<P style="MARGIN-TOP: 4pt" class=MsoPlainText>Who knows?<o:p></o:p></P>

<P class=MsoPlainText>As long as we don't place the tar laden charcoal in the
soil but use it as a fuel. In other words clean charcoal added into the soil is
much better that adding charcoal that was used to filter toxic waste.
