Paul et. al.,
I am a particular fan of "nutrient-enhanced biochar slurry" and other
nutrient-biochar complexes (i.e. organic NPK-C fertilizers).
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 *Mr. Gord
Fraser* of /*The Ravina Project*/ (CC'd).
[Although of course these tests were not done in weathered and
degraded soils in suboptimal agronomic systems, but were instead done in
Community Gardens.]
see:
http://www.theravinaproject.org
note: This is the first time I have heard referenced the term, "/flame
curtain/ 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.
It is also good to know that the biochar that was produced by the
"flame curtain pyrolysis method, "was of excellent quality, qualifying
for /premium quality /of the European Biochar Certificate".
Does anyone know if any of the (TLUD) "Stove biochars" have ever been
able to qualify for such a designation? (i.e. "/premium quality/" under
the "European Biochar Certificate".)
I could imagine that perhaps with a fan and very consistent feedstock
-- eg. pellets -- it /might/, 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.?
P.S. I have also not yet seen any practical /*Energy* applications/ for
the (excess) heat that is produced by a Cone Kiln. (Not even for
cooking.. or heating water etc.)
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 /utilize/ the heat in another practical process, at the same time
that the char is being produced?
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. /Agriculture/ document -- has
always been one of the attributes of the TLUD stove that has made it so
attractive.
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
/appear/ to the casual observer that all of that heat energy from the
biomass is being "wasted"...)
