Paul et. al.,<br>
<br>
I am a particular fan of "nutrient-enhanced biochar slurry" and
other nutrient-biochar complexes (i.e. organic NPK-C fertilizers).<br>
<br>
I read through the attached "Agriculture" Technical Note by
Schmidt et. al. and came across the line stating that, "no
scientific study has yet been undertaken to investigate the
fertilizing properties of urine-enriched biochar", however although
this may be true among "mainstream" academic studies [prior to this
study being published], I do know of one [1] other medium-term well
controlled scientific study of urine-enriched biochar has been done
here in Toronto by <b>Mr. Gord Fraser</b> of <i><b>The Ravina
Project</b></i> (CC'd).<br>
[Although of course these tests were not done in weathered and
degraded soils in suboptimal agronomic systems, but were instead
done in Community Gardens.]<br>

<br>
note: This is the first time I have heard referenced the term, "<i>flame
curtain</i> pyrolysis" (to describe the process that occurs in a
Cone kiln). It seems an apt name, and seems similar to the process
that occurs in a TLUD stove, although the flame front travels in a
different direction, and there is no requirement for ongoing
additions of new biomass (to the top of the burn pile) with a TLUD.<br>
<br>
It is also good to know that the biochar that was produced by the
"flame curtain pyrolysis method, "was of excellent quality,
qualifying for <i>premium quality </i>of the European Biochar
Certificate".<br>
<br>
Does anyone know if any of the (TLUD) "Stove biochars" have ever
been able to qualify for such a designation? (i.e. "<i>premium
quality</i>" under the "European Biochar Certificate".)<br>
<br>
I could imagine that perhaps with a fan and very consistent
feedstock -- eg. pellets -- it <i>might</i>, but how about without
a fan, and with, for instance, wood chips, nut shells or other farm
residues such as straw, husks, animal feed left over, shrubs,
cuttings and prunings etc.?<br>
<br>
P.S. I have also not yet seen any practical <i><b>Energy</b>
applications</i> for the (excess) heat that is produced by a Cone
Kiln. (Not even for cooking.. or heating water etc.)<br>
Has there been any testing and/or advancements made in this area
such that a Cone Kiln might also be used for cooking or any other
task that might <i>utilize</i> the heat in another practical
process, at the same time that the char is being produced?<br>
<br>
note: The practical "duel" application for TLUD stoves -- i.e.
serving as a cooking instrument (Stove) that can also produce
biochar, which is hopefully of a sufficient quality for acceptable
use in methods similar to those described in the Schmidt et. al. <i>Agriculture</i>
document -- has always been one of the attributes of the TLUD stove
that has made it so attractive.<br>
It would be nice to see a Cone Kiln that has been adapted for some
sort of "duel use" as well. (At the very least so that it does not <i>appear</i>
to the casual observer that all of that heat energy from the biomass
is being "wasted"...)<br>

4. Do not expect to find your answers in a
reference book from 2009. Even now in 2015 it will
be difficult to find the "conclusive" type of proofs
that you are seeking. Part of the reason is that
there is so little money into biochar field trials.
And SOOOOOO many variables that even good results
can be challenged. The status of "proof" about
biochar benefits might be akin to the status of
"proof" about climate change 30 years ago, or 10 yrs
ago., and there are still plenty of deniers about
climate change today. Biochar research has a
loooooooong way to go. Much work needs to be done.<span

5. Personally, I am a "biochar believer" (within
reason) and am increasingly active on biochar
work. But do not ask me to "prove" it. I am
going with my hunches, similar to how I got started
with TLUD stoves 15 years ago, and only in recent
years is there some noteworthy acceptance. I hope
that biochar can have faster results, but there can
be only a few growing seasons per year even in
greenhouses.<br style="line-height: 1.22em;"
