A LA ABEJAS: TWO OJAI FARMERS AT TERRA MADRE

the
main hall at Terra Madre
|
We have
been running Churchill Orchard, our little citrus spread in
the Ojai Valley, for a number of years now. We've been involved
in a variety of projects that support local agriculture and
better food, and we're members of the local Slow Food chapter.
Every other year Slow Food sponsors the Salone del Gusto,
a big meeting in Italy. We were already making plans to attend
when we heard about its 2004 sister event, Terra Madre - Slow
Food's ambitious international conference of 5,000 small food
and fiber producers. The local Slow Food chapter sponsored
our application and we were on our way.
As the
Oct. 19-23 conference approached, the lack of logistical details
forthcoming from Terra Madre's organizers hinted at the magnitude
of their task: 5,000 delegates from 128 countries to be housed,
fed, transported, and translated. A few weeks before leaving,
we blinked and booked a hotel room in Torino (Turin) near
the conference site. Four days before departure, we received
a housing assignment. We decided to keep our hotel, and forego
the crazy, last minute accommodations (and the great stories
we'd get out of it.) And off we go.
TUESDAY
- Our Terra Madre starts in the Frankfurt airport. A dozen
food artisans from the Western U.S. drift in - jet lagged,
excited - for the last leg of the trip to Torino. We see Tim
Bates and Karen Schmitt from the Apple Farm in Philo, holistic
range management mentor Alan Savory, peach grower/author Mas
Masumoto, Albert and Vivian Straus of the Straus Dairy farm
family, and Richard and Candace Spiegel, a pair of single-flower-honey
artists from Hilo, Hawaii. Everybody's curious about what
the next few days will bring, and nobody knows much. But all
are game.
We land,
check in, and board a bus to the conference site, a '60s-modern
aircraft hangar called the Palazzo de Lavoro. Hitting the
lobby is a rush - milling around and dozing on top of their
luggage are people from every corner of the earth. What ever
else happens over the next four days, these people will make
the trip worthwhile.
WEDNESDAY
- Opening plenary is scheduled for 3 p.m. We arrive early,
soak up the scene, and compare notes with our fellow Californians.
We are rare birds - citrus farmers from Southern California.
Fisherfolk, livestock producers, honey producers, cheese producers
are present in larger numbers. Northern California is well
represented.
We
score our headphones, and settle into our seats in the big
theater. The opening ceremonies are magnificent and moving
and reveal more of the political agenda of our hosts and their
strategy for engaging us. The international Slow Food movement
was born in Italy, and hospitality may be the primary mode
of Italian communication. We are welcomed by a singing group
from a nearby Alp, who pass a large bowl of wine and drink
as they sing. The drinking song extends the wine bowl and
drinking challenge to the mayor of Torino, and a couple of
esteemed and exotic delegates. Then the master of ceremonies
invites one delegate from each country to mount the stage
and take a seat as the roll call of countries is recited.
The roll call is moving; when the natural dignity of ordinary
people is honored by other ordinary people, the result can
be extraordinary. We are addressed by Slow Food founder Carlo
Petrini, and by Vandana Shiva, Alice Waters, the mayor, the
governor, and Italy's Minister of Agriculture and Forestry.
We are all feeling pretty honored by now, and awed by our
role as pieces of this pageant.
Stuff
we learned
The basic
plan seems to be to use the general assembly to describe the
looming threat on the global horizon: mega-consolidation,
genetic modification, falling commodity prices as a dwindling
pool of ever-larger suppliers tightens their grip. Honor the
participants, and rally the troops to turn back the tide of
those forces threatening farming traditions and cultures all
over the world.
Physicist,
author, and environmentalist Dr. Vandana Shiva delivered a
real stem-winder of a speech, and her central metaphor has
stuck with us. "The world is still eating World War II
leftovers," she said. Modern agriculture, based on petrochemical
fertilizers, herbicides, and pesticides, was developed during
WWII. The U.S. - one the few corners of the globe where war
was not raging - was called upon to feed the rest of the world.
Maximum production was the highest priority. This style of
agriculture, she said, "wages war upon the soil, air,
and water, and war upon our bodies." She referred to
the World Trade Organization plan for a globalized agriculture
as waging a "war on farmers, and a war upon the earth."
She called for a new agriculture based on economies of peace.
Since Vandana planted that seed, we've been thinking about
how agriculture requires peace; you cannot farm in a war zone.
North America's geographic isolation (and our talent for exporting
our war to other parts of the world) has allowed us to farm
in peace for 150 years, even as generations of displaced farmers
from less fortunate regions have immigrated to the U.S. to
pursue their livelihood.
THURSDAY/FRIDAY
- Workshop sessions allow delegates to tell stories of small-scale
successes in their local regions, but there are no workshops
for citrus growers. So Lisa opts to check out the honey workshop
- a beehive of beekeepers from 36 countries encountering each
other for the first time. The scheduled speakers are dispatched
quickly and unscheduled beekeepers swarm the moderator to ask
for a few minutes to add their story. It seems there's a lot
more to honey than something you stir into your tea - it's an
important factor in the economic viability of many small farmers.
Some examples:
| |
Subsistence
farmers in Kenya have developed commercial honey production
as a way to generate enough income to preserve their forests
intact. Their neighbors without a honey program are forced
to burn the trees to produce commercial charcoal, their
only means of raising the small amount of hard currency
they require to survive. |
| |
Italian
beekeepers explain that Italy has 20 registered varieties
of single-flower honeys. The head of the Italian beekeepers'
union deplores the state of industrial commodity honey
- it has "no soul," and customers' honey preference
is based on the picture on the honey label. |
| |
In
Costa Rica, shade coffee growers develop a coffee-flower
honey business to help support the forest that that shades
their coffee trees as they try to weather the coffee-bean
price collapse. The Costa Rican beekeeper said it well:
"We must create value for what we seek to defend.
Gracias a las abejas." |
| |
Brazilian
beekeepers have been producing commercial honey for export;
they are still waiting for permission to sell in Brazilian
supermarkets. |
| |
Mike,
the only registered beekeeper in the city of London, gathers
bee pollen from an assortment of London neighborhoods
and city parks, and sells this neighborhood-specific pollen
to local allergy suffers. |
The
stories roll on: Honey used as medicine in the Caucasus
and in Mexico, cliff-scaling wild honey hunters from Nilgiris
in India, a honey museum in Belarus, the stingless Mayan bee
used as a cataract treatment. Armenia, Kenya, Gambia - a rich
tapestry of art and lore, commerce and competition unrolls.
A few concerns surface over and over: pesticide use can threaten
the bees and contaminate the honey. Loss of bee habitat can
end production. All the beekeepers present (except Mike from
London) plan to sell their increased production of honey into
the world export market, and there was widespread sentiment
to organize quickly in order to maintain the honey's value
and quality. Who knew that honey made such a difference in
the world? We buy two jars of Italian "bitter" chestnut
honey to take home.
While
Lisa soaked up the buzz on honey, Jim attended a session on
"Designations of Origin as a means of raising the profile
of a local area." The idea is that the producer of a
traditional product registers a trademark on the product,
the production method, and the place of origin, with the European
Community; the consumer, in purchasing the produce, purchases
not only a product but also a set of values and a documented
story.
As Pixie
tangerine growers in the Ojai Valley, we're trying to do something
similar - create a "terroir" for Ojai Valley Pixie
tangerines in the absence of any framework permitting or tradition
supporting this. In Europe, where they have food traditions
extending back centuries, local food traditions are formally
recognized and receive legal protection. Think of wines from
Burgundy or Gorgonzola cheese.
The first
speaker shows slides documenting centuries of cheese production
traditional to the Monte Rossa Valley in the Italian Alps
(you can see a lot of wonderful information at www.macagn.com).
The attributes of the cheese have much to do with life in
this Alpine valley: the particular grass that the cattle eat,
and the fact that the water is 800 meters below the meadows.
The cheese goes to market on mules, because there are no vehicles
up there.
The second
speaker represents tribal producers of guarana, a high-caffeine
tropical berry, in the Brazilian jungle. Traditional native
producers of guarana are threatened by new intellectual property
laws, as local breweries and the likes of Pepsi and Coke seek
patents locking up ways to utilize guarana for their own beverages;
and by the forces of industrial ag, as cattle production threatens
both the jungles and the bees essential to the cultivation
of guarana. He pleads for help from Slow Food to protect traditional
methods of beekeeping, and called for "participatory"
research to learn about traditional methods of production,
and not only "official science."
Jim is
both struck and moved by the extraordinary knowledge and care
that goes into the production of traditional products in disparate
parts of the world.
Scenes
from the marketplace
Terra
Madre organizers wisely (or inadvertently) have left a large
corner of the convention space empty. It does not stay empty
for long. Quick-witted delegates have traveled to Torino with
bulging suitcases, and they quickly set up an instant farmers'
market/international trade show. Our tangerines being out
of season, we have nothing to demo but we linger in the marketplace
between sessions, enjoying the improbable odd couples sharing
demo tables. One favorite trio is a buff Haida gentleman from
British Columbia offering succulent smoked salmon. The handsome
Haida's neighbor, a waifish Siberian Russian from Sakhalin
Island, offers samples of four wildcrafted teas: leaves and
flowers of the forest, a meadow mix, a blend of wildflowers,
and a mixture of seven wild berries. To drink this tea is
to be transported to the rich chilly forests of Easternmost
Asia. The tea drinker's neighbor is a witty and opinionated
Maori chap from New Zealand, who offers samples of abalone
with a side order of indigenous fishing rights.
Closing
time
SATURDAY
- We all convene for the closing session. The wonderful assemblage
of national representatives in native costume is swamped by
an admiring throng of camera-toting delegates and international
press.
Winona
LaDuke, Anishinaabeg tribe, Minnesota producer of native wild
rice, four years ago the Green Party candidate for vice president,
reminds us of the basics: "Whether they have fins, whether
they have wings, whether they have hooves, whether they have
roots, whether they have four legs, whether they have two
legs, they are our relatives, and we are absolutely dependent
on them, and we are no better than them." Her eloquence
moves Jim almost to tears; afterwards he asks her for a text
of her talk and she replies, "You know, I didn't write
it down." Well. (It turns out you can find much of her
message in a small book, "Food Is Medicine," available
from www.honorearth.org
or at 800-EARTH-07.)
Something
that probably wouldn't happen in the United States is that
important public officials stand up and align themselves and
their agencies with the goals of Terra Madre: Enzo Ghigo,
the President of the Regional Authority (equivalent and then
some to one of our governors), promises that his region will
be GMO-free as long as he is governor. The Minister of Agriculture
and Forestries, Gianno Alemanno, notes that of the many "agricultural"
conferences he has attended, Terra Madre is the first to put
actual farmers and food producers at the center of the stage.
He tells us we (that is, the world) must decide whether to
recognize that the production of food is different from other
WTO preoccupations because it must reflect local differences.
We must end pitting farmers against farmers, and we must end
nonfarmers profiting at the expense of farmers. Trade must
enhance farming rather than spoil its lands. The living world
must be protected from the demands of profit and intellectual
property rights. From these speeches, we hazard an interpretation
that perhaps industrial agriculture has gotten so big that
entire countries, such as Italy, have decided they're unable
to compete, and that sustainable agriculture is in their interest.
Perhaps Italy is setting out to organize the international
search for another viable way, and wouldn't that be wonderful?
During
this final session, phalanxes of Central Casting security
agents fill the hall: buff, wearing suits and sunglasses,
with little wires running to earpieces. We happen to be in
on a secret (that the surprise final speaker is to be Prince
Charles) so the security presence doesn't seem out of place.
When the
Italian public officials are done speaking, they all leave.
And with them goes the entire security squad, who seemed to
have been protecting the Minister of Agriculture. Evidently
it's dangerous business to argue that the living world must
be protected from the demands of profit and intellectual property
rights. Much more dangerous than being Prince of Wales, because
there is no noticeable security presence after they left.
Still,
we haven't reached the end! Slow Food founder Carlo Petrini
speaks to us of three worlds: "One is poor, ruined, and
needy; another is balanced and sustainable; yet another is
rich but committed to an unsustainable lifestyle. Beware,
you of this rich world; you can no longer profit by exporting
your poisons to the south. Farmers and scientists must begin
to work together."
Mr. Petrini then introduces the closest thing the United States
has to food royalty, Alice Waters, who introduces His Royal
Highness, Charles, Prince of Wales.
Prince
Charles addresses us with humility, humor, and great eloquence.
You can find the entire text of his talk at slowfood.com
(look under sloweb); here are excerpts:
"
Imposing
industrial farming systems on traditional agricultural economies
is actively destroying both biological and social capital
and eliminating the cultural identity which has its roots
in working on the land. It is also fueling the frightening
acceleration of urbanization throughout the world and removing
large parts of humanity from meaningful contact with Nature
and the food that they eat
"
"
The
missing ingredient in these great plans is always sustainable
livelihoods and its absence increases the existing, awful
drift towards degraded, dysfunctional, and unmanageable cities
.
It is a sobering thought that almost all of the next one billion
of net global population growth (over the next 12 to 15 years)
will take place in urban slums.
What will these conditions
breed for the future? Hopelessness, crime, extremism, terrorism?
Who will deal with these chickens when they come home to roost
on a globalized perch?"
"
the
importance of your Movement cannot be overstated
After
all, the food you produce is far more than just food, for
it represents an entire culture - the culture of the family
farm. It represents the ancient tapestry of rural life; the
dedicated animal husbandry, the struggle with the natural
elements, the love of landscape, the childhood memories, the
knowledge and wisdom learned from parents and grandparents,
the intimate understanding of local climate and conditions,
the hopes and fears of succeeding generations. You represent
genuinely sustainable agriculture, and I salute you."
A neater
summation of Terra Madre there could not have been. We left
inspired and humbled both.
OJAI
- A GROWER'S PARADISE

Ojais lush landscape
|
By Camille
Sears
Whenever
two food growers meet for the first time, the conversation
will inevitably begin with this simple question: What are
you growing? This is true for backyard and balcony gardeners,
small family farmers, and owners of giant operations measured
in square miles. And while this may be an oversimplification,
it seems to me that most growers fall into two broad groups
- those who plant as many different crops as they possibly
can, and those who focus on one or two main products.
By nature,
small gardens tend to include an abundance of variety. Who
can browse the annual seed catalogs and not be enticed by
the thousands of options presented there? I couldn't. Growing
up, I spent hundreds of hours glued to Gurney's seed catalogs,
dreaming of gardens that would include nearly every flower
and vegetable that the friendly folks in Yankton, South Dakota,
could provide. It didn't matter that my growing space was
very limited; I was hopelessly infected with the diversity
bug that afflicts so many gardeners.
And being
raised in Ojai's favorable climate only fueled this disorder.
Few places on our planet have conditions that allow so many
different crops to flourish as they do here. Summer and winter
vegetables, citrus, avocados, stone fruits, apples, pears,
walnuts, pomegranates, figs, olives, lavender and other herbs,
and even subtropicals like cherimoya and sapote are found
thriving in Ojai. From a grower's standpoint, it's like being
a kid in a candy store. I sometimes wonder: By what restraint
do certain people plant only one crop?
I've
been fortunate to have my hands in Ojai's soil for most of
my life. And even though I was nestled in this gardener's
paradise, I sometimes dreamed of places that offered specific
growing conditions not found here. In my 20s, a decade in
which I was nearly obsessed with winemaking, I explored the
possibility of growing vineyards in Yamhill County, Oregon,
or in the Santa Rita Hills east of Lompoc. And after the December
1990 freeze leveled our bananas and papayas, my family cautiously
listened to my ideas of relocating to warmer and wetter climes.
With not-so-hidden rolling eyes, they entertained my search
for farmland near Brisbane, Australia, and later, Hilo, Hawaii.
In the end, however, I came to realize that we were already
in one of the most favorable growing places on earth. Besides,
we could always buy an Oregon pinot noir or a bunch of bananas,
right?
And so,
in 1996, we purchased a dilapidated local orange orchard,
moving us from backyard gardeners into the family farmer category.
After clearing the land, chipping up the old trees, and planting
cover crops, we were faced with this question: What can we
grow?
The short
answer is: Just about anything. And this presents a problem
for people like me, who can't seem to focus on one or two
single crops. In writing this, I realize that in the past
year we grew over 150 different varieties - mostly tree fruits.
Yes, I know how much easier life would be if I planted a monocrop
orchard. Cultural practices, harvesting, and marketing would
be effortless compared to the way we do it now. But if we
are to discover the best cultivars for Ojai, experiments with
diversity are essential. That's my logical rationale anyway;
the drive to grow "just about anything" is still
there.
Although
most local growers focus on orchards today, Ojai was once
home to more row-crop farms. A few years ago, as I was weeding
our orchard nearest the road, an elderly gentleman stopped
his car and came to talk with me. He told me that when he
was a child, this was a wonderful tomato field. This makes
sense, as Ojai's summers are relatively warm, and we have
a long frost-free period. Summer annuals are sure to grow
well here, especially if the heat-loving crops such at tomatoes,
peppers, and melons are planted in early summer, after our
May gray and June gloom have left us. For instance, I try
to delay seeding melons until June 10, to take advantage of
the 100 warmest days in our summer.
But it's
the wide range of fruit tree possibilities that makes our
area remarkable. I can't think of a better place anywhere
to grow an almost unlimited variety of fruits. It's not much
of a stretch to say that we can grow just about any citrus
and stone fruit, and many subtropicals. In poring over the
hundreds of citrus acquisitions archived at UC Riverside,
and the thousands of deciduous fruit tree specimens grown
by UC Davis, I never feel limited by our climate on what we
can grow.
This is
because Ojai is uniquely situated. In most years, we get nearly
the same winter chill as Santa Ynez, which allows our stone
fruit to thrive. Our winter low temperatures are sufficiently
cold to grow all but the highest-chill deciduous fruit trees.
On the other hand, we are south of the Transverse Range, in
an area providing nearly ideal conditions for citrus. True,
most growers protect their citrus trees at least a few nights
each winter. But in most years, no protection is really necessary.
There are thousands of backyard trees, and numerous orchards,
that prosper without any frost control measures. The downside,
of course, is a risk to the citrus harvest when that periodic
hard freeze visits.
Freezing
weather aside, this is truly fruit tree grower paradise. And
if one is fortunate to have both valley floor and hillside
growing conditions, the possibilities are even greater. On
the surrounding hillside slopes, nighttime lows are considerably
warmer than the valley floor where the cold air drainage settles.
On cold nights, I've measured 40-degree temperatures on Saddle
Mountain while it was 23 degrees on Creek Road, only a few
hundred feet directly below. The warmer nights in elevated
terrain means that one can grow more tender avocados, like
the Hass variety, as well as many subtropicals. There is a
trade-off, however, as the hillsides and slopes tend to have
poorer soils than the valley floor.
These
principles were well known to a family friend, Mr. Peirano,
whose ranch was located across the entrance to Lake Casitas.
By taking advantage of the various microclimates on his land,
he grew many kinds of fruits and vegetables. His farm and
house are now gone, although remnants of his place still remain.
About 10 years ago, I was given permission by the Casitas
Municipal Water District to go to his old homesite and collect
whatever plant material I could find. Guided by fading memories
of the orchards and gardens, I walked the land from top to
bottom. At the lowest (and coldest) parts of his property,
there were cactus pears and grapevines. Along the road up
the hill were apricot and pomegranate trees. Up higher, I
found avocado and sapote trees. And this is only a fraction
of what Mr. Peirano once grew - everything else (including
his figs and citrus) was removed. Joyously, I came home with
scion and budwood from his apricots, pomegranates, and grapes.
I passed over the cactus pears (it's a long story, involving
my tongue and a pair of tweezers). Even I have limits.
And while
our orchards are on the valley floor, we grow roughly half
citrus and half deciduous fruit trees. In most years we have
plenty of chill for our apricots, plums, pluots, peaches,
and nectarines, while staying just above the cold-damage limit
for citrus. In all honesty, I believe that much of the Ojai
Valley is better suited to stone fruits than citrus. With
lower water and nutrient demands, and fewer concerns about
freezes, deciduous fruit trees are a natural for Ojai.
But there
is much more than just being able to grow food crops. Variety
or mass production without quality is futile in our demanding
marketplace. Thankfully, Ojai's climate allows us to grow
a huge variety of fruits, and with outstanding quality across
the board. Ojai's warm summer days and cool nights, and resultant
large swings in daily temperatures, tend to create fruits
with a wonderful sugar-acid balance not usually seen in areas
with hot days and warm nights. This is something that wine
grape growers have known for centuries. For example, if the
same cabernet grape cultivar is grown in a place with warm
summer days and cool nights, such as Paso Robles, and a place
with both warm days and nights, such as the Central Valley,
the sugar-acid balance and character of the wines will be
completely different. This is an illustration of terroir,
that quality of wines attributable to the conditions where
they are grown. The terroir factor also applies to fruits
such as apricots, plums, peaches, and yes, citrus.
The key
is to match the right varieties to the place where they are
grown. In Ojai, some citrus growers have been true pioneers,
experimenting with the Pixie tangerine when most farmers ignored
it. Our climate and geography produces Pixies that have favorable
size, color, rind conditions, sweetness, and acidity that
have not been duplicated elsewhere. And Pixies are just the
beginning. Identifying more varieties that exhibit outstanding
and unique local qualities is essential to bringing recognition
to Ojai's crops, and making them stand out amongst the competition.
As our
farm grows out of its infancy, I see our collection of crops
evolving into fewer varieties based on the best selections.
This is part of the learning process, as some varieties are
simply better suited to our place than others. No matter how
hard I try, our Noir des Carmes or Prescott Fond Blanc melons
will never be as sweet and flavorful as our Petit Gris de
Rennes. Our Santa Rosa, Shiro, and Burbank plums, while very
good, can't compare with our Larodas. And it's more than just
sweetness. Our Flavor Queen pluots, even at 26 Brix (about
26% sugar), have a hint of acidity to them. But are the fruits
better tasting or more identifiable at 23 Brix, with somewhat
more acid? I'm slowly discovering that harvesting and marketing
are just as important as growing the right varieties.
Ojai growers
know that our citrus and other fruits are unbeatable for color,
flavor, and other qualities. But how do we convey this to
the general public? How does Ojai, with myriad crop options
and limited growing area, become known for what we grow? We
can start by identifying Ojai as a unique growing region,
in both geography and climate. The rest will take time - Ojai's
agricultural experience is limited compared to most parts
of the world. After a few more generations of experimentation,
we will certainly know more about what does best here, and
how to coax every nuance out of our harvests.
Others
may disagree with me, but I think the ultimate goal of a grower,
on any scale, is to go beyond quality and to capture the essence
of place in the crops we harvest. If we're persistent, we
can bring out the unique characteristics of the fruits we
raise - the flavors, textures, and fragrances that are enhanced
by our local climate and setting. We should strive to grow
produce that will remind those eating it that, without a doubt,
it comes from Ojai. In other words, it must not only look
and taste great; the crop should also reflect the terroir
of this place.
I believe
that capturing a quantifiable local influence in the food
we grow is an important, yet attainable task. But there's
more to Ojai than we can possibly measure. When I walk our
orchards, and sense the sheltering mountains that surround
us, it's hard not to be charmed by this valley. And on certain
evenings, after Vespers and Mass at St. Joseph's, I'm inexplicably
drawn to the surrounding East End orange orchards, where the
light, smells, and lingering memory of the Angelus bells seem
to magnify this enchantment. I wish there were some way to
convey this essential quality of Ojai to others, through our
crops.
CLOUD COVER ON A WINTER'S NIGHT IS
A FARMER'S FRIEND
By Emily
Thacher

smudge pots and wind machines
dot the Ojai Valley |
A year
ago my Aunt Aleta London and I were talking over lunch about
taking care of orchards and she reprimanded me for not knowing
what an EOT was. After finishing lunch I went home and called
my brother and asked if he knew what an EOT was. After finding
out he didn't know, I called my aunt's son, Robert, and he
didn't know either. So I deduced that my entire generation
didn't know what an EOT was, a sure sign of a lack of our
parents passing information on to our generation. I returned
and told my aunt that I was stumped. In fact, nobody from
my generation knew what an EOT was.
The answer
is an Engine On Top, a reference to the type of orchard wind
machine that requires climbing up to the top of the tower
to start it. In Ojai electric wind machines have replaced
many EOTs with engines on the bottom. Others have been taken
out altogether. Wind machines are expensive to buy, maintain,
and operate. Many farmers have simply chosen not to have them
anymore. But they do have their place in the world of crop
protection.
I've heard
lots of opinions and ideas about the wind machines - sometimes
incorrectly called "windmills" - that dot the orchards
of our valley. They are indeed machines designed to create
wind. (A windmill is a device that harnesses the energy of
the wind in order to run machinery.) Why on earth, you might
wonder, would farmers want to generate wind? And could those
few machines generate enough wind to accomplish anything?
There
are several reasons farmers like wind. Wind can be used to
dry orchards. It is not pleasant to pick fruit when trees
are wet, whether it be Pixie Tangerines or Bing cherries.
In fact, if cherry or citrus fruit is picked when wet, its
skin becomes loose and the fruit will decay. To effectively
pick quality fruit, orchards must be dry, which is why you
see picking crews working on just about any dry day during
the spring in California. This is also one reason cherry farmers
may use wind machines or even helicopters to facilitate drying
orchards. It is unlikely that a citrus farmer would use a
wind machine to dry an orchard for picking. Citrus holds better
on a tree than cherries and we can generally wait for a dry
day to pick.
So why
do Ojai ranchers have wind machines? The answer is frost protection.
From November to April Ojai can get an occasional frost damaging
enough to freeze citrus fruits and sometimes even cold enough
to kill the young trees. Many of our frosts occur when there
is no air movement through the Valley from the coast. As a
valley, Ojai can trap cool air as cold air sinks and heat
rises. Avocados are quite sensitive to frost, which is why
they are planted on the slopes, above the areas where cold
air settles. Wind and natural airflow - which, in Ojai, follows
the Valley's drainage from the northeast to southwest - help
to mix cold and warm layers of air. A layer of cold air trapped
below a layer of warm air is called an inversion layer. Wind
machines are tall enough that they can be turned on to mix
the warm air from above with the cold air below and break
the inversion layer. If the ceiling of warm air isn't too
far up, effective use of wind machines can raise the temperature
as much as 10 degrees!
A wind
machine is essentially a propeller on a tall post. They sound
and function just like a propeller from an airplane, which
is why the posts must be bolted tightly to a hefty concrete
base. When a wind machine is operating, the propeller turns
so fast that it becomes a blur and makes the treetops rustle
with the wind. They are very powerful, moving massive amounts
of air. You don't want a wind machine to "take off,"
although this is not unheard of. My neighbor, Harry Sims,
told me the story about one of the wind machines at the Kokx
Ranch taking off. Harry heard a great noise one cold night.
The next day he went over to take a look and the propeller
and engine (it was an old EOT) had come apart from the base
and flown about 100 feet into the orchard, removing several
mature orange trees in its path. Luckily, nobody was hurt.
This is one reason why wind machines tend to be located some
distance from houses.
Another
reason is the noise. Wind machines are loud. They run on propane,
gasoline, or electricity. You may have been awakened by the
pop-popping of wind machines starting up in the Valley on
cold nights as you sleep cozily in your warm bed. The start-up
sounds are then followed by the faintly audible whirr, accompanied
by others starting up. If you live close enough, that whirr
can grow into quite a roar. If the noise bothers you, take
a deep breath, think about the farmers out in the cold working
to save their crops, and thank them for the green space around
you.
Some
wind machines have automatic starters, set to go off when
the temperature dips below 30 degrees or so. Others must be
manually started. On a cold night you will hear them starting
up at all hours after sunset. When you hear them, you know
it is below 32 degrees, there is an inversion layer (or so
the farmers believe), and that your farming neighbors are
not going to get a good night's sleep.
There
are other methods of frost protection. The least expensive
and first line of defense is to increase moisture in the orchard
by irrigation. Dispersing water evenly over an orchard as
a means of frost protection is a concept that only began in
the 1980s with the installation of our current irrigation
systems. Water has a high heat capacity; water from wells
at 60 degrees radiates lots of heat before freezing - and
even more while changing from water to ice. The dew point
is also critical; the temperature drop will stall if the dew
point is above freezing and there is enough water in the air
such as after a rain or when there's a good onshore flow from
the ocean. Your lips and nose will also appreciate the extra
moisture in drier winter air.
Cloud
cover at night is a farmer's best friend in the winter. A
clear, starry night promises a rapid temperature fall after
dark. The more moisture present, the harder for the air temperature
to drop, as the moisture must freeze before the temperature
plummets below 32 degrees. Icicles hanging from the bottoms
of trees after cold nights make an awesome sight yet don't
always indicate a hard freeze.
The second
line of defense, if there is a good inversion layer, is a
wind machine. As a last resort, some farmers and nurserymen
still use orchard heaters (also called smudge pots.)
If used
effectively, orchard heaters can raise the temperature as
much as 10 degrees simply by adding radiant heat to the environment.
Smudge pots have saved the California citrus industry multiple
times over the past 100 years. They are now very expensive
to run, as each one burns about 10 gallons of diesel a night.
Unless they happen to have an old supply of diesel oil, most
growers have abandoned the use of smudge pots; it's just too
expensive. Smudging has also come under fire as a source of
air pollution. It has not been outlawed, as there is no better
alternative for cold nights in which there is no inversion
layer. Ojai ranchers are well aware that smudge pots dirty
the air with soot, yet believe that a few nights of soot is
a small price to pay for saving a newly planted grove or the
income from an orchard.
Historically
the coldest night of the year has been December 24, a night
when nobody wants to stay up smudging, followed by a day when
nobody wants to wake up to our Valley with dirty air. Yet
it is the two weeks around Christmas and New Year's that citrus
farmers have their ears most attentively tuned to agricultural
weather reports and it's the reason that generations of my
family and many other ranchers never leave the Valley for
the holidays.
At what
temperature and time to start frost protection is a delicate
situation. All methods of protection are expensive, so using
them at the mere possibility of frost is a waste. My dad believes
that frost protection is the hardest thing to learn about
Ojai farming - just as every winter rainstorm is different,
so is every frost. An offshore breeze, upper air moisture
or any number of climatic factors can influence nightly temperatures
in our small valley. Citrus can withstand 28 degrees for a
few hours. Small fruit and fruit with less sugar is more susceptible
to frost damage; lemons and small, immature tangerines are
more sensitive than oranges. As a rule of thumb, frost protection
is advisable at 28 degrees for lemons and Pixies, and 27 for
other citrus, whether the low temperature is steady or intermittent.
Yet if the temperature doesn't drop this low until 3 a.m.,
it's not worth the energy to warm the orchard for just a few
hours as water and fruit take time to freeze and the temperature
will rise again at dawn.
Or, if
the temperature (god forbid) is 27 degrees at sunset and dropping,
you may as well have a few nips of brandy and call it a night
unless there is a good inversion layer and wind machines can
raise the temperature effectively.
Often
there are several cold nights in a row, so previous lows influence
decisions for subsequent cold nights. The valley floor is
not flat and the temperature on one side of an orchard may
be four degrees different from the other side, so where to
begin frost protection within an orchard is yet another factor.
To add to the complication about when to use frost protection,
the value of the crop should be accounted for: If the fruit
that will freeze is only worth $1 a box, why bother spending
$3 trying to save it? Yet if you save your fruit and nobody
else has any, you may be able to demand $30 a box, so perhaps
some frost protection is worth it?
Judging
how low the temperature will drop and for how long is almost
an art form. It's important to remember that in a hard freeze
it's essential to save the tree even if the crop is lost.
Most of us in farming listen for neighbors' wind machines
and make our decisions based on who is doing what. Harry Sims,
Bob Davis, Jim Coultas, my Aunt Aleta and dad Tony are some
of the old hands I know who have been through enough cold
nights to make some educated guesses about when to do what.
For now I am paying attention to what they are doing and may
be one day able to make my own decisions based on what I learn
through them.
Later
in my conversation with my aunt I ventured so far as to admit
that I have never started a wind machine - so far that job
has been left to others. Already this winter (starting Nov.
28) I have learned and am now in charge of checking temperatures
and turning on machines in the dead of night. Luckily, we
don't have any EOTs; I'm thankful to not have to climb up
a very tall machine on a cold night and be shaken by the thunderous
roar of the wind blowing by as I make my way down the steep
ladder to the ground. I am hopeful to never experience a wind
machine "taking off" - or, for that matter, one
catching fire, as one of my neighbor's did just last week.
Now let's all hope for a warmer and wetter winter. There's
lots of excellent fruit in store for next spring if the weather
stays above freezing!
