<div class="moz-cite-prefix">Thanks for copying me on this response,
Crispin.<br>
<br>
I am also very happy whenever I hear of yet another "success
story" with "undifferentiated Biochar" produced from small
gasifier "stoves" and used in crop production. Of course, the
Biochar is almost never used <u><i>alone</i></u>, but is used
alongside other amendments ["<span
style="font-family:"Arial","sans-serif";color:black">different
formulations</span>"] like "<span
style="font-family:"Arial","sans-serif";color:black">mulch,
compost, crushed bone, crushed coral, lava dust, and generally
any animal and green waste</span>"...<br>
(My most recent conversations I am having had to do with the
complimentary use of "rock dust" ~ a.k.a. "agrominerals" and
Biochar ... The use of 'agrominerals' is a technique that [unknown
to me until recently] has actually been honed by many folks at the
<i>University of Guelph</i> over the past several decades. With
Biochar one should be able to create high quality inoculated
bio-chars that help to "free" the agrominerals [rock dust] of
their 'nutrients' at a more accelerated rate.)<br>
<br>
I have always felt that the role of Biochar was to "<span
style="font-family:"Arial","sans-serif";color:black">even
out the soil moisture retention capabilities of the soil</span>s".
I actually expressed this exact sentiment to David Laird -- and
others -- personally at the first North American Biochar
conference in 2009 in Colorado, though it was not in those terms
exactly. What I had found remarkable was the ability of Biochar
placed into my CLAY soils to actually help my [potted] plants
survive (induced) "drought" -- a totally counter-intuitive
outcome.<br>
I had suggested that it was likely the <i>nature</i> of the
"water-holding ability" of Biochar that was the benefit: i.e. the
ability of the chars to hold onto water, but not too "tightly" ~
which thus allows the water to be fairly easily 'unbound' from the
char surfaces by the root systems and fungi and other living
fractions of the soils. (The same is likely true for the
relationship between chars and many 'nutrients'...)<br>
<br>
As I also wrote recently in an unrelated thread, "I actually
suspect that by combining... (all of these other things) with
Biochar (and "soil microbes/fungi" etc), that we might be <b>making
our lives </b><b><u><i>easier</i></u></b> [rather than more
complicated] -- in terms of actually achieving "fertility
benefits" through the addition of these amendments... Although
the <b><i>science</i></b> of actually 'teasing it all apart' to
understand <u><i>exactly</i></u> what is going on in terms of the
complex interactions that are taking place between the soils,
minerals, plants and biology will probably get <u><b>more</b>
complicated</u> and thus more expensive/difficult to perform.<br>
In my mind, this complexity does <u>not</u> <i>necessarily</i>
mean that we will not be able to achieve <i><b>quicker results</b></i>
in terms of "food security" ~ and Climate security [mostly via <i>adaptation</i>],
however.<br>
<br>
As I concluded, I wrote that, "a LOT more learning needs to be
done to understand the various influences all of these amendments
are actually having on the soils and the biology -- and the best
techniques for how to restore 'balance', 'vibrancy' and perhaps
also (some modicum of) 'stability' to the LIVING FRACTION of the
soils -- especially from the additions of Biochar."<br>
<br>
As David Yarrow wrote once, "<i>ultimately, this Biochar thing
isn't really about chemistry or carbon; it's about <b>biology</b></i>".<br>
Don't forget: Nature offers us some extraordinary design solutions
-- honed by 3.8 billion years of rigorous testing.<br>
To me, what Biochar is really all about is our attempts at
>making permanent <b>humus</b>< <u><i>faster</i></u>.
Humus is an amazing soil conditioner. Only 5% humus can transform
lifeless 'rock dust' into a rich loam. It has abilities to both
bind sand and granulate clay.<br>
<br>
Have you watched the film, "<i>HUMUS: Forgotten Climate Aid</i>"?<br>
The film documents the use of Biochar to help, "unravel the
secret of <i>sustainably fertile soil</i> and find solutions for
building up humus". (The film documents the many years of work
that have been done in the Styrian "Eco-region of Kaindorf"
[Germany], and features many notable Biochar proponents like Dr.
Christoph Steiner and others who use "agrocraft"** -- to build
"targeted humus" ~ even in relatively Fertile soils. [!] )<br>
<br>
** Agrokraft GmbH was created by the <i>Bavarian Farmers
Association</i> to explore concepts and technologies like
hydro-thermal carbonization (HTC), with the support of the <i><b>Max
Planck Institute for Colloids and Interfaces</b></i> in
Potsdam (near Berlin).<br>
<br>
"Agrokraft" is also often referred to as "<i>Climatefarming</i>"
~ an attempt at reproducing "Terra Preta-like" soils.<br>

I cannot give you the type of answer you are hoping
for. I produce food, not run experiments using
various percentages of char, different formulations,
and using controls. In addition, I use a number of
soil amendments including char, mulch, compost,
crushed bone, crushed coral, lava dust, and
generally any animal and green waste that comes
available. None of my field is amended by biochar
alone. I also make and use foliar sprays when plants
show need.<o:p></o:p></span></p>

style="font-family:"Arial","sans-serif";color:black">Having
said that, I saw visible improvement in the areas
that I started using biochar. The plants were
visibly more lush and withstood dry conditions
better. My own reasons for adding biochar is that it
tends to even out the soil moisture retention
capabilities of the soil. The areas that became
boggy now drain better. The areas that moisture
levels fluctuated wildly now tend to flatten out
somewhat, staying much more evenly moist. In my own
situation, I found that leaving the char chunky (
1/4 to 1 inch) works just fine. <o:p></o:p></span></p>
