The debate goes on although I think
it is high time we went in another direction.
First off, chemical farming shows
us how an optimized farm growing protocol could actually look. Now we know.
Sustainability was always a huge question and that drives the real
debate.
Organic methods are slower to implement
but can come close to meeting our demands for productivity on some soils.
The real revolution that is
slowly getting of the ground is the biochar agricultural revolution.
This protocol consists of adding
elemental carbon to the soil each year, preferably made directly from plant
wastes locally available. The idea is to
sustain this until the working soil retains a ten percent elemental carbon
content.
As this is established, nutrients
are accumulated and recaptured back into the soil as a natural sustainable
process and the leaching of soils ends outright. In the end it is a perfect compliment to
organic methods.
More dramatic, this protocol
recovers waste land soils to full productivity and allows soils presently
unusable to be used fully.
The Economist dismisses organic ag, while also making the case for it 102

This isn't the only way.I've been reading The Economist's "Special
Report on Feeding the World" (intro here). So far, it's typical Economist:
compellingly written and impressively broad in scope -- but largely uncritical
of the status quo. The report doesn't bring much new to the table, especially
to those of us who follow the gloomy macro-analyses of thinkers likeLester Brown.
Predictably enough, The Economist's perspective on the
"feed the world" question is guided by the assumption, never much
examined, that only high-tech, massive-scale farming can tackle the task of
feeding the 9 billion people expected to be on Earth by 2050. The series' lead editorial frames
the question like this:
[While] the concerns of the critics of modern agriculture may be
understandable, the reaction against intensive farming is a luxury of the rich.
Traditional and organic farming could feed Europeans and Americans well. It
cannot feed the world.
From The Economist.Forget, for a minute, that this statement warms
over a stale agribusiness talking point: there is no alternative to
corporate-dominated agriculture. Instead, take a look at the chart,
reproduced at the right, lifted from the top of this very same editorial. The
chart describes average wheat yields under different forms of agricultural
management at the Broadbalk field in England 's famed Rothamsted Research
station. The Economist describes the Broadbalk field like this:
Broadbalk is no ordinary field. The first experimental crop of winter
wheat was sown there in the autumn of 1843, and for the past 166 years the
field, part of the Rothamsted Research station, has been the site of the
longest-running continuous agricultural experiment in the world. Now different
parts of the field are sown using different practices, making Broadbalk a
microcosm of the state of world farming.
You don't have to look very closely at the chart to see that fields
treated with manure produce roughly identical yields to those treated with
"inorganic fertilisers," i.e., synthetic nitrogen, mined phosphorous,
etc. In other words, based on the Broadbalk experiments highlighted by The
Economist itself, there's no reason to assume, a priori, that
organic farming "cannot feed the world."
Next, dig into the Rothamsted center's own
report [PDF] on its experiments. There, you'll find that the Broadbalk
fields treated with manure not only deliver roughly equal yields, but also are
better at building up both organic matter and microbial activity in the soil --
both critical measures of soil health.
It's puzzling that a special series premised on dismissing organic
agriculture would lead with a chart that vindicates it. Organic agriculture
probably can feed the world at least as well as the
agribusiness-driven variety. It's just that it can't feed the minds of The
Economist's editors, who are fixated on images of gigantic machines
dispersing agrichemicals onto vast fields monocropped with GMO seeds. When it
comes to envisioning the future of agriculture, the magazine's thinkers appear
to suffer from what Vandana
Shiva has called "monocultures of the mind."
