We are either quenching our biochar with pig pee or, where we are working
in fields where the stuff is too damn heavy to bring along, we are just
soaking our biochar with as much as it will hold.
Our initial test results suggest that the biochar soaked with pig piss is
going rice faster than biochar and manure.

You can get very good results without using compost just by quenching the
hot biochar and/or soaking the biochar in urine from animals or feeding to
animals and putting the biochar dung mixture directly in the ground
Saves a lot of work. Look at Hans Peters work. My colleagues in Vietnam
are making biochar and quenching both with urine dung straw and soil and
then putting back in a pit next to the animal pens to allow to mature.

Dennis, I agree with you biochar and compost belong together.
But if I were in a third world setting I would focus my labor on
producing compost imminently, no stoves needed, and biochar later.
Most of the soil scientists I know are retired.

I accept the importance of compost in the context that you refer to it.
However I am convinced that it is not an 'either or' but a combination of
the two. These materials are fundamental to soil health, but for small
scale farmers labour intensive to make and use.in many environments. So
for the farmers effort I think biochar has the ability to add value to
compost in both the short and long term. Compost can be very short lived
and nutrient management is paramount.
It is largely shameful that many of the soil science community are not
voicing concern at the rapidly deteriorating health of food producing soil,
and I am in total agreement with your statement
"Soil health may be how we will feed the rapidly growing population, and
enabling soil health may be the only way to aggressively counter
anthropogenic carbon emissions".
But as Micheal points out, rather than debate at an academic level, it is
preferable to have action on the farm, particularly if couched in
considered analyses of information available.

For me personally, I am disciplining my work within the theoretical

Sticking with that theoretical construct forces you to consider your

Another point you make around all the research that has been done not
much seems to have come from it. I agree.
Perhaps however this situation should not be a surprise. Revolutions are
ugly, and this one may have particularly high stakes.
The world of agriculture has been focused on improving yields through
genetics, and fertilizers, and is approaching a plateau. I believe, and
pray, that we are at a nexus in soil health.
Soil health may be how we will feed the rapidly growing population, and
enabling soil health may be the only way to aggressively counter
anthropogenic carbon emissions.
I understand your desire to have local, low cost biochar machines, to
support the impoverished, and that "never ran across evidence that putting
properly produced biochar in degraded soils will make them worse".
For really bad soils, that may be true.
I will argue however, that compost is more important for severely
degraded soils, and we should not forget its importance in promoting
microbial life. Biochar is primarily fixed carbon, and outside of
providing porosity to the soil to get needed oxygen to a micro biome, its
not the type of carbon microbes need to function.
And unlike biochar, which requires years in the soil before it shows its
potential, compost is at full impact immediately.
We are dealing with the most vulnerable people on the planet.

*Subject:* Re: [biochar] New biochar publication (#2)
I am so new to the list that I am not even sure that this is the proper
way to respond to an ongoing discussion. If nothing else, I apologize for
the length of what follows, which falls into two parts, one which addresses
the "debate" per se and the other provides suggestions.
I follow these many biochar groups from afar because I literally live far
away in the mountains of North Thailand. My primary mental occupation
reading the posts is to translate them into information useful to the
people I work with/for - extremely poor smallholders working very marginal
mountain soils. Quite apart from the fact that I lack the remarkable
scientific credentials that all of you possess - I trained as a political
scientist and owe what I know about biochar and sustainable agriculture to
hands-on field work - I will admit that I often find reading these threads
Three things stand out about the discourse. First is the lack of
civility, remarkable even to someone who spend 30 years at a major
university. Second, and I am sure closely related, is the common practice
of diminishing the importance of the task at hand for the ends of
self-promotion. Third, and most important, is the regular failure to pursue
a constructive, collective research design effort that would - one would
hope - begin to generate a better, broader, rather than still more
fragmented understanding of our subject.
I do not think that my first point requires much elaboration. Anyone who
has served in an unhappy department recognizes the signs of a dysfunctional
community in these threads. Until we can learn to bite our tongues, show
some basic respect for others and demonstrate a capacity to go along to get
along, biochar, as a field of research, will continue to see much of its
energy spun off in personal spite. Such a waste. So many opportunities
As for my second observation, I am all for naming really big discoveries
for really great discoverers. Higgs certainly deserves to get his boson
named after him. But the frantic efforts to name biochar "technology"
strike me as both pathetic and indicative of this same underlying
dysfunction in the field. We are, after all, talking about "technical"
variations in what are really jumped-up charcoal makers. Anyone in my old
field who tried to rename a theory for himself/herself because (s)he
re-jiggered an index would be laughed out the door. The project is not
about ego and ego gratification, it is about better understanding biochar
and how to make it better.
Which leads to my third observation. Having trained in the social
sciences, I am used to the mockery of "hard" scientists who ask: "So,
what's scientific about politics?" The answer, of course, lies in how you
study it. And here is where I have been most disappointed with the research
on biochar. Despite the inevitable complaints that there must be more of
it, what strikes me as an outsider is how little effective use has been
made of all of the effort that has been poured into research already.
I can think of two reasons for this, one easily dismissed and one cause
for a challenge. The easily dismissed reason is simply that most research,
most of the time is tediously reductive. If it is observed that different
feedstocks produce different biochars, then "testing" different feedstocks
- one after another after another - qualifies as research. Biochar, like
all fields, is full of such "research."
To put it colloquially, what drives me crazy, especially as an outsider,
is that even the good research does not seem to cumulate to anything
tangible. I have never in my life encountered another field with so many
"on the one hand...but on the other hands" without any clear efforts to
establish an embracing theoretical construct, even at the middle level. In
biochar, it seems, every result is not only important, it is equally
important, such that there is no fixed ground, all is detail, all is fact
This observation, based on a huge amount of "innocent" reading, brings me
back to the thread regarding the proposed new journal and its assertion
that "Biochar has been a very popular research topic and a large amount of
scientific literature has been produced in the last decade...However,
before proceeding to recommend massive use of biochar in soil, more
research is necessary to have enough knowledge and understanding of biochar
This assertion leads me in three directions. First it leads me to ask:
Where is the big research design? What is the project we are all working
on? What is all of this 'research' supposed to add up to?
Here, I must say, I am impressed by this particular thread's emphasis on
actual field testing by extension agents. If these guys are out convincing
real farmers to test stuff and not simply running tests in 10x10 plots,
then we are getting somewhere, we are getting to the point that scientists
are forming coherent research questions related to real world performance
that can be tested in the real world. It is precisely this lack of coherent
research questions - coherent in the sense that they constitute meaningful
questions and coherent in the sense that they coher with one another - that
I have missed most in the black hole that is biochar research.
Second, I really have to ask: what is all this for? I do understand the
imperatives of funding and so the fact that biochar research tends to be
climate change and energy funding driven. But there is still a very, very
big world of agriculture out here that has, or I suppose I should say
"ought to have" a big interest in biochar. Yes, there is some research on
biochar and this crop or that crop in this field or that field here or
there. But Christ on a Crutch, can you use biochar to improve your egg
plant yield? I mean, here I am running an incredibly under-funded,
over-extended nonprofit at the edge of the world and the only way I can
tell my farmers that biochar will help their corn is to conduct field tests
for them? Do I have the time (or the money) for this? And, jeez, if no one
is conducting basic research like this on farm performance in the developed
world, when the hell is anyone going to get around to doing it for the
developing world? Where do you think people live? Who do you think needs
Sorry. Got carried away.
Third, and in line with the challenges set out by critics in this thread,
the peculiarities of biochar research, specifically, its intense commitment
to specification, lead me to ask: where are the competent vulgarizers of
the huge, existing biochar literature?
What do I mean?
Let me close by trying to put this in the context of the work that I do
and by trying to explain why the call for lots of new research before we
begin to talk about using biochar on a large scale drives me crazy.
I am not a research scientist, although I do conduct randomized plot,
multi-replicate, multi-year tests of biochars. I am not interested in
refinement. I am not interested in customization. I *am *interested in
risk - but as regards the call for further research, despite all of my
reading (including not only edition 2 of the "bible" but most of the cited
articles in the relevant chapters), I have never run across strong evidence
that putting basic, properly conditioned biochar into degraded soils will
make them worse.
I live in a world where the average income is below $1.50 a day, where at
current levels of technology 2/3's of the population cannot support
themselves on the land they "own," where soil pH is 4.5 to 5, OM is under
1% and there is often no soil microbiota. I live in a world where everyone
burns all of their field waste, where particulate inhalation kills infants
and old people and reduces the labor capacity of "healthy" adults. I live
in a world typical of the large "fringe" of the developing world where our
2.54 billion poorest people live.
I have lots of challenges, but in my thinking, biochar (as I have learned
about it) lies at the heart of a coherent, if partial, solution to some of
the leading ones. Producing biochar from field waste stops GHG, dioxin and
particuate emissions. In the soil, biochar sequesters CO2, mitigates
climate change risk by retaining water, improves soil structure, raises pH,
and promotes microbiota growth. It also improves yields, adding to farmers'
Note: I am talking about one "biochar" - and for a reason.
I live in a world in which: (1) farmers have no control over the
feedstock they use; (2) the technology available to farmers is homemade and
permits no modulation of temperature; (3) farmers cannot test their soil;
and (4) farmers will plant whatever they are going to plant.
Where I live, there are no variables; there is just "biochar" - the stuff
you get. Based on my reading, I have come to the conclusion that despite
all of the specifications, there is, in fact, some*thing* that we can
call "biochar" that has sufficiently common, good attributes in our soil
that it merits not only using, but pushing.
The challenges confronting me are therefore to: (1) design biochar
machines that will accept all shapes and sizes of feedstock; (2) design
biochar machines that can be made locally from scrap metal; (3) demonstrate
to farmers (and myself) that whatever biochar they can make will "work" in
whatever soil they have; and (4) demonstrate to farmers (and myself) that
whatever biochar they can make will "work" in whatever soil they have with
whatever crop they need to grow.
This is not an insignificant challenge for many reasons. Anyone who are
worked in very poor, rural communities will understand what a challenge the
basic extension is. But more to the point, what matters is not what I can
demonstrate here with the few thousand farmers in our villages; what
matters is that if this works, it can be replicated all over the developing
world with important climate change, health and poverty reduction effects.
- Farmers' in the developing world produce 330 gigatons of black
carbon annually burning their fields. Were any significant portion of this
converted to biochar, the climate change impact would be big.
- The annual conversion of any significant portion of field waste to
biochar and its application as a soil conditioner would also sequester
millions of tons of CO2,
- The elimination of black carbon (mostly PM2.5 and smaller) would
reduce the incidence of respiratory and cardio-vascular disease, and
stroke, and infant mortality and premature death rates.
- The availability of biochar soil conditioner would increase the
crop yields of the poorest farmers the most, reducing poverty and improving
No amount of further research about the specifics of the biochars
produced by additional types of feedstocks will do these people any good.
What I need is the opposite: I need research about the basic
commonalities of biochars and its (biochar's) performance is commonally
encountered soils with the most common staple and cash crops of the
developing world. This is not the research agenda mentioned above, which
will serve developed world farmers well. They can control for almost all
variable and with irrigation can even adjust for rainfall. Their research
needs are for the performance characteristics of customized biochars for
specific soils and crops - something that any high-tech developed world
biochar manufacturer can easily produce. My research needs are the
opposite, and I lay them out below.
Now, my needs are obviously entirely different from the needs of the
research science community. But then, what I think is revealed in this
thread is that "biochar" the subject is not one, but many.
Perhaps it is time that we stopped asking everyone to be everything.
Perhaps it is time that we recognized that there are different biochar
constituencies out there - and that these different constituencies began to
formulate their needs from each other into actionable requests rather than
As for myself, I think that there are substantial, reseach-consuming but
action-oriented communities interested in two distinct areas:
1. Biochar and climate change globally, whether in the developed or
developing world. This mandate might be broadened to biochar and the
environment to include biochar and non-climate change related environmental
issues such as soil and water decontamination.
2. Biochar and the developing world, including climate change and
environmental issues in general, sustainable agriculture, food security,
In each instance, I would suggest that the pubications be written for an
interested and informed public, not fellow researchers, in order to make
them readily available to IO and INGO staff, that articles be in English
with abstracts in 1 or 2 other international languages, and that they
include limited citations to key references.
As for actionable requests, here are mine as a member of both of these
- Is it possible to develop additional compilations of chemicals
biochar can adsorb or otherwise cause to break down along the lines of the
work started by Josh Kearns?
- Note 1: Here specifics about biochars may be unavoidable, but in
presentation, perhaps attention can be paid to categorizing groups of
biochars by performance rather than simply listing alphabetically.
- Is it possible to conduct a meta-analysis to identify the common
characteristics of biochar in degraded soils?
- Note 1: This will surely require a similar meta-analysis to
identify the common characteristics of biochar.
- Note 2: This will surely require the specification of a short
list of major degraded soil types, the purpose of the exercize being to
relieve the user of the need to have highly detailed soil maps (generally
not available, at least not with GPS capacity) or farmers to have soil
tests (again, generally not available).
- Is it possible to develop field-tested data regarding
best-practices for application rates and means for different crops?
(As in my classes when I still taught, the rule is "no criticism without
a constructive alternative.")
Behind both requests lies a common request: please remember your audience
and think "communication."
Please bear in mind that you have two audiences: audience of fellow
scientists and an audience of biochar practitioners who need your results
presented in a clear and compelling fastion. Please take Prof. Toufte to

We are disappointed because we have not followed the tried and proven
path to commercializing new products in the agriculture industry.
Look at the websites of biochar companies. There are broad claims, at
best with a reference to a proof of concept experiment. But where does it
say "grow 50% more tomatoes" and where does it tell you exactly how to grow
more tomatoes (apply x tons per acre, incorporate into the soil six inches,
etc). And where is the guarantee? I am not aware of any.
So if you are farmer, or any user, why should you be compelled to risk
spending the money to use biochar, without specific claims? Where is the
data? Who can I call at the State, what is the number of the regional
extension scientist that will validate what you are telling me? OOOPS
*[RWL7: There have been huge past federal budgets for topics less
valuable than biochar. Biochar has an unreasonable hurdle - because it
happens to (without conflict) help on both soil and climate fronts. The
fact that it can displace fossil fuels makes it even harder to get
Congressional funding. (In the US only).*
Even on this blog, lots of ideas (which is great), opinion, no data, no
statistics. no third party validation. (Wood Vinegar is a recent
example). Some introduce new variables, no data. Mix up all kinds of
concoctions, no statistics. Science requires that a claim be measurable and
repeatable. we all need to remember this.
*[RWL8. Governments routinely expect to support science - to support
research. I am agreeing with you here.*
Wood Vinegar. I learned some people are selling it in California without
CDFA approval, makes us all look bad.
And I will note that there is LOTS of biochar out there. For gods sake
don't build a biochar machine for the business purpose of making biochar.
Call a charcoal company if you need some. Its actually a great start for
us, no capital, low cost, we all need to leverage to develop the markets.
*[RWL9: Certainly a lot of research is going on with char intended for
a barbecue. I hope that new biochar researchers (funded or not) will still
engage in science - and do tests appropriately.*
So I disagree with you, and Hugh. We need more experiments. Identify
the product and application. Start with claims, and then get the data to
prove claims. Get the extension scientists or leaders in the agriculture
industry on board, pay them to do the work. These is not the experiments
that leading academics do, but rather the work of agronomists, and
university extension scientists.
