This is a great story about a
leading California
strawberry grower who successfully converted over to organic methods thirty
years ago and is now the most successful operator out there. The first take home is that it is certainly
possible.
The second practical lesson is
that it requires a three year conversion period of some belt tightening which
is no serious problem if the farm is paid for but trickier otherwise. Once that initial investment is made, organic
methods soon generate yield and quality improvements.
A third comment that I would like
to make, is that all such operations also need to implement biochar production
lines to add biochar to the seed hills or rows to stabilize the nutrient
loading. That can eliminate much of the
ongoing need to fertilize.
The big story is that conversion
takes three years and productivity will match or supersede the industrial
protocol.
We are also entering a market in
which the consumer will simply demand organic and buy inferior stock so long as
it is organic. The grower can not afford
to be a last resort supplier as supply chains get better at differentiating the
two products. Very soon, I suspect non organic will be known as poor people's food as was the case long ago.
Strawberry grower shows how to make a profit without poisons

This story was written by Laura Fraser.
Along California 's rugged coastal
Highway One, just north of Santa Cruz ,
a yellow vintage pick-up truck and tidy rows of strawberries mark the entrance
to the Swanton Berry Farm. Inside the cheerful farm stand, decorated with old
photos of the region and fluttering United Farm Worker flags, locals gather at
blue picnic tables, sipping coffee, eating strawberry shortcake, and chatting
with Jim
Cochran, the owner.
The air is scented with the first berries of the season. They're fresh
and sweet, intensely red and fragrant, and firm -- not pumped up with nitrogen
like most commercial strawberries. Cochran, 63, a silver-haired man with an
easy manner and quietly fierce intelligence, takes evident pride in watching a
visitor savor one. He was California 's
first organic strawberry grower, harvesting his initial crop more than 25 years
ago.
"From the start, everyone said it was impossible to grow a
commercial crop of strawberries without chemicals," Cochran says.
Over the years, he has proven them wrong, showing the $2 billion California strawberry industry -- which accounts for 88
percent of U.S.
strawberry production, and 20 percent worldwide -- that it is economically
viable to grow strawberries on a large scale without using toxic fumigants and
pesticides. Cochran's success flies in the face of industry claims that farmers
need to use harmful chemicals on strawberries in order to stay in business.
Environmentalists and public health experts are trying to stop California from
allowing farmers to apply a known carcinogen to their fields (as a replacement
for another chemical that damages the ozone layer), and Cochran's big flats of
beautiful berries -- and his healthy balance sheet -- are proving crucial to
that fight.
Cochran says that he initially grew strawberries just like everyone
else: using pesticides and fumigants. Then, in 1981, he was poisoned. One early
morning he was standing in a field wondering if the cropduster had sprayed
pesticides overnight. When the sun came up, he found out in the worst way: the
heat and light activated the chemical, turning it into a cloud of tear gas. The
next year, he was doused by methyl bromide -- as, he says, are most of the
workers who lay and pull up tarps that enclose the gas in the soil. Those
episodes left him feeling sick and shaky, with temporary respiratory problems.
They faded after about a month, he says, and he never went to the doctor or
reported them to the health authorities -- it was just considered a hazard of
working in the fields. But he didn't want to permanently damage his health, so
he decided to try farming organically.
"This was when it was becoming obvious that pesticides were way
more harmful than people had been led to believe," he says. At the time,
Cochran was working for a co-op that didn't want to take the financial risk of
trying to grow berries organically; the owners said that without fumigants,
they'd likely lose the whole crop. Strawberries are far more expensive to grow
per acre than most crops -- about six times what broccoli costs, for example --
and they're very finicky, prone to soil diseases, mold, and other maladies. So
Cochran and a partner decided to start their own strawberry farm, but hedged
their bets by planting half the crop using conventional pesticides and
fumigants and half without them.
At first, the organic crops didn't do as well, but it was no disaster.
Cochran and his partner saw a decreased yield of about 20 percent in the
organic crop, he says. They sold those berries at a 20 percent premium, but
because of other costs involved in organic growing, such as rotating crops and
using more labor-intensive techniques to control weeds and pests, they were
barely breaking even.
Cochran's partner left, but he continued the experiment. He was single
and could afford to live cheaply, building a small cabin by hand, in order to
save money for his crops. He tried various methods of increasing yields, using
different composts, planting methods, and organic fertilizers, pesticides, and
fungicides. He discovered that rotating broccoli and cauliflower with
strawberry crops improved the health of the soil, and he found that planting
strawberries in single rows, instead of the usual multiples, allowed more air
to circulate, thus decreasing mold.
Cochran also began working with researchers at the University of California
at Santa Cruz
to perform randomized studies of his organic and fumigated crops. During the
late '80s, he says, it was difficult to get funding for such research from the
industry group, the California
Strawberry Commission. "The industry blockaded our efforts to get
money to research alternatives, and spent a lot of money in Washington making sure our proposals didn't
get funded." (The commission began funding such research ten years later).
In 1989, Cochran and the Santa Cruz
researchers published a study showing that growing strawberries organically was
economically viable with the techniques he had developed, since the premium for
organic berries covered most of the increased costs of farming. The study
piqued other farmers' interest.
"They saw that it's possible to grow organic strawberries,"
he says. "It's not that it's a hugely amazing technical advance, it's just
that somebody had to go out and do something differently and not get killed
financially." In 2002, Cochran was awarded the EPA's Stratospheric Ozone
Protection Award for his techniques. On Thursday, the Natural
Resources Defense Council will honor him with a Growing Green Award.
Still, a quarter century after Cochran harvested his first crop of
organic strawberries, only 4 percent of California
strawberries are grown that way. The rest -- some 34,000 acres -- still rely on
fumigants and pesticides that are hazardous to the environment and to human
health.
Under the 1989 Montreal
Protocol, an international treaty designed to save the ozone layer, and an
amendment to the 1998 Clean Air Act, the ozone-depleting fumigant methyl
bromide, which conventional strawberry growers depend on for sterilizing their
soil to control weeds and diseases, was supposed to have been phased out by
2005. It has survived with "critical use" extensions from the EPA,
based on industry claims that there are no technically and economically
feasible alternatives to the chemical.
Now there is, but while it's better on the ozone layer, it appears to
be even worse on human health. Methyl iodide was approved by the EPA in 2007,
under the Bush Administration, despite widespread scientific reports --
including studies produced for the EPA and the California Department of
Pesticide Regulation -- that it is toxic to humans. California, which has its
own additional review process, approved the fumigant last year under outgoing
Gov. Arnold Schwarzenegger, though with more stringent regulations than the
federal ones, including greater buffer zones between the crops and human
activity, and smaller amounts used per acre. The approval bucked the advice of
the California Department of Pesticide Reform's own scientists and a committee
of independent university experts. New Gov. Jerry Brown's administration has
put the fumigant on hold pending further review.
"Methyl iodide is a very potent mutagen and genotoxic
chemical," says Dr. Gina Solomon, a senior scientist and public health
expert at NRDC. "It damages DNA." If inhaled by farm workers or
nearby residents, says Solomon, the gas could cause neurological damage,
cancer, and fetal toxicity. Thyroid poisoning could occur if the iodine seeps
into groundwater. "The science is quite clear on this chemical, and
there's a dramatic disconnect between the science and the California policy."
Cochran testified before a committee of the California State Assembly
in 2009, saying that it's perfectly possible to produce strawberries without
either methyl bromide or methyl iodide and make a profit. "Last year, I
was probably one of the most profitable [strawberry] companies in the entire United States ,"
he says.
Other farmers are beginning to listen. The California Strawberry
Commission, made up of the state's 500-plus strawberry farmers, is now funding
research on alternatives to the two chemicals, says spokeswoman Carolyn
O'Donnell. "We really are trying to find some solutions here; we're not
just taking the next thing off the shelf." The group has funded studies on
alternative fumigation techniques, such as crop rotation, mustard-seed meal,
and sterilizing the soil with solar energy. "We're trying to find a mix of
things -- it isn't one size fits all." O'Donnell says that methyl bromide
use has declined 50 percent in California
since the Montreal
Protocol, despite the extensions, and that farmers are increasingly looking at
alternatives.
But going organic, she says, is expensive and time-consuming. It takes
three years for land to be certified organic, during which time the farmer
can't sell the crop at a premium to cover the increased costs of production.
"So you're taking a loss in yield potentially and unable to recoup it with
a higher price," O'Donnell says.
But Cochran has little sympathy for growers cowed by the transition
process. "It's surprisingly easier to grow strawberries without chemicals
than the industry would lead you to believe," he says, adding that there
are "plenty of competent farmers" demonstrating as much. Meanwhile,
farmers have known for 25 years that methyl bromide would need to be phased out
and are just now playing catch-up. "They're 15 years behind where they
should be," he says, "and it's their own damn fault."
Cochran acknowledges that it will probably take a generational shift
for strawberry farmers to fully come around to organics. Most farmers his age,
he says, are too comfortable with their methods, and too old to want to change.
But he's optimistic that their children will make the shift, and that more and
more consumers will understand the risks posed by conventional berries.
Cochran looks out across his fields, where birds are pecking at fruit,
and he scowls at a gopher popping his head up close to the succulent berries.
It's true that his strawberries take a lot more work and cost to produce, and
the bottom line is that organic farmers like Cochran can only survive -- and
other conventional farmers will only risk a transition -- if consumers are
willing to pay an extra dollar a basket for their product. But biting into one
of Cochran's strawberries, it doesn't seem to matter for a moment that the air in
these fields is clean, and that the berries don't harm the ozone layer or
people's health. They just taste better.
