It is really simple. A weight of root below ground produces a similar weight above ground. Thus the most important aspect of production is to maximize the bio weight that is underground. This should have been perfected centuries ago but has obviously not. Now it is been applied by improved spacing and the crop responds. Of course the use of organic fertilizers provides an additional influx of full spectrum nutrition that ensures optimal production also.
Now
imagine adding a steady dressing of biochar to the organic fertilizer
a and meet goals that seem impossible.
The
only thing that is still difficult is handling the organic component.
That part is labor intensive and needs to be smartened up if that is
possible. A lot can be converted to biochar through drying and
heating yet a portion does need to be rotted down in order to produce
biologicals we barely recognize yet. Otherwise it would make far
better sense to dry everything and fire it all through a fast kiln to
make biochar as that captures all the chemistry.
In
the future, every farm will need a drying shed. Since it is not too
hard to turn stuff over and air drying is quite good enough, even a
couple of weeks are sufficient to make the material bin ready. That
means a later crop can also be handled easily.
Miracle grow: Indian farmers smash crop yield records without GMOs
By
Tom

What if the
agricultural revolution has already happened and we didn’t realize
it? Essentially, that’s the idea in this
report from
the Guardian about a group of poverty-stricken Indian rice and potato
farmers who harvested confirmed world-record yields of rice and
potatoes. Best of all: They did it completely sans-GMOs or even
chemicals of any kind.
[Sumant] Kumar, a shy young farmer in Nalanda district of India’s poorest state Bihar, had — using only farmyard manure and without any herbicides — grown an astonishing 22.4 tonnes of rice on one hectare [~2.5 acres] of land. This was a world record and with rice the staple food of more than half the world’s population of seven billion, big news.
It beat not just the 19.4 tonnes achieved by the “father of rice”, the Chinese agricultural scientist Yuan Longping, but the World Bank-funded scientists at the International Rice Research Institute in the Philippines, and anything achieved by the biggest European and American seed and GM companies. And it was not just Sumant Kumar. Krishna, Nitish, Sanjay and Bijay, his friends and rivals in Darveshpura, all recorded over 17 tonnes, and many others in the villages around claimed to have more than doubled their usual yields.
Another Bihar
farmer broke India’s wheat-growing record the same year. They
accomplished all this without GMOs or advanced seed hybrids,
artificial fertilizer or herbicide. Instead, they used a technique
called System
of Rice [or root] Intensification (SRI).
It’s a technique developed in Madagascar in the 1980s by a French
Jesuit and then identified and promulgated by Cornell political
scientist and international development specialist Norman Uphoff.
SRI for rice
involves starting with fewer, more widely spaced plants; using less
water; actively aerating the soil; and applying lots of organic
fertilizer. According
to Uphoff’s SRI
Institute website [PDF],
the farmers who use synthetic fertilizer with the technique get lower
yields than those who farm organically. How’s that for pleasant
irony?
The breadth of
the results in Bihar have gotten international attention. The
Guardian reports that economist Joseph Stieglitz, a Nobel laureate
and international development aficionado, visited the area last
month. After seeing their amazing results, he declared the farmers
“better than scientists.”
High praise
aside, the technique is not without its detractors. Most western
governments and agricultural scientists remain skeptical of the
practice: Many challenge that the reported yields aren’t verified,
there’s insufficient science behind the technique, and they worry
it can’t scale to larger farms.
Achim Dobermann,
deputy director of worldwide standard-bearers the International Rice
Research Institute (IRRI), dismissed the technique in comments to the
Guardian:
SRI is a set of management practices and nothing else, many of which have been known for a long time and are best recommended practice … Scientifically speaking I don’t believe there is any miracle. When people independently have evaluated SRI principles then the result has usually been quite different from what has been reported on farm evaluations conducted by NGOs and others who are promoting it. Most scientists have had difficulty replicating the observations.
Given the paucity
— or total absence — of independent testing done on GMOs and
pesticides developed by companies like Monsanto and Syngenta, it’s
galling to read of scientists complaining “there is not enough
peer-reviewed evidence around SRI” and that “it is impossible to
get such returns.”
Here’s where
the potential conflicts of interest crop up: The IRRI is
currently involved in developing GMO rice as
a core component of a campaign to increase yields worldwide. This
doesn’t entirely invalidate its position on SRI, but it points to
the ideological divide in agriculture between those who believe in
technology as the only solution to “feeding the world” and those
who put faith in non-technological, agro-ecological techniques to
accomplish the same.
(It’s also
worth noting that the regions in India that invested heavily in
Monsanto’s GMO RoundUp Ready cotton seeds are
seeing yields collapse;
Monsanto blames
the crop failure on farmers.
Grist reported recently on the
even deeper tragedy many
of these farmers are experiencing.)
Much of this
divide comes from a belief among many scientists and most western
governments that the developing world must adopt western-style
industrial ag techniques in order to produce enough food. But that
view is a fantasy: Even today, as the Guardian article observes, 93
percent of Bihar’s 100 million residents are subsistence farmers.
It’s delusional
to expect that Bihar and the vast populations of Africa, Indonesia,
and China will transform into western-style economies with
western-style population distributions. Billions of people across the
globe will remain subsistence farmers far into the future; what they
require are farming techniques that can improve yields even modestly.
Forcing regions that don’t have passable roads (much less
electrification) to rely on the grace of multinational organizations
to supply seeds, fertilizers, and chemicals seems borderline
criminal.
SRI appears to
offer an acceptable alternative for
a variety of crops,
including rice, potatoes, wheat, corn, beans, eggplant, onions,
carrots, sugar cane, and even tomatoes.
For many
westerners, including many
western
journalists,
it’s difficult to separate the concept of “progress” from its
inevitable modifier, “technological.” SRI may not be
technology-based, but it’s science-based and sophisticated. It’s
also continually field tested and improved through farmers’ own
feedback. It’s exactly the kind of flexible, responsive system
you’d demand from any truly sustainable agriculture — as opposed
to the regimented, top-down application of chemical- and
biotech-based approaches.
Plain old western
snobbery shouldn’t be discounted, either. As agronomist Anil Verma
put it in the Guardian article:
If any scientist or a company came up with a technology that almost guaranteed a 50% increase in yields at no extra cost they would get a Nobel prize. But when young Biharian farmers do that they get nothing.
Does SRI need
more research? Absolutely. Can it be adapted to large-scale monocrop
agriculture? Probably not. But that’s exactly the kind of
agriculture that’s failing us and needs to be reassessed entirely.
Where does SRI go
from here? In India, at least, Bihar alone is investing $50 million
in expanding adoption. However, the Guardianreports that “Western
governments and foundations are holding back, preferring to invest in
hi-tech research.”
Meanwhile,
Monsanto shows no signs of slowing down: Indications are that it will
win its patent case before
the Supreme Court and gain virtual total control of its seeds. This
will enable it to continue charging inflated prices for a technology
that provides modest
yield increases,
if any, and certainly nothing close to the 30-percent increase many
agronomists are praying for.
It’s always
possible we’ll wake up to the successes being pioneered by the
unlikeliest of subjects — subsistence farmers in the far east.
Until then, Monsanto’s technology-driven vision of agriculture is
winning here in the west.
