Charlie Hitchings has been growing
organic blueberries for thirty years at Spring River Farm in Cherryfield and
actively cultivating them for almost a decade.
On May 10, researchers and scientists from the University of Maine Orono
and Maine Organic Farmers and Gardeners Association (MOFGA) gathered there to
observe the results of his labors. This
was the first conference to be held on a grower’s fields under the aegis of The
Blueberry Organic Transition Project, which seeks to establish best practices
for growers of low bush blueberries who wish to move from conventional methods
to organic growing methods.
Blessed with a beautiful sunny
morning, they followed Charlie over hill and dale, through woods and across
streams to the barrens on a corner of his 400-acre farm, to observe his methods
and results first-hand. Any time one
inserts oneself into the natural order of things, life gets complex, but
Hitchings is trying to work with Mother Nature as much as possible.
Therefore, the compost heap, that
backbone of organic practices, was the first stop on the tour. Here project leader, Frank Drummond,
Professor of Insect Pest Management, Department of Biological Sciences,
University of Maine, began the lively questioning that Hitchings enjoyed
throughout the two-hour field trip. As
might be expected, Eric Sideman, Director of Technical Services, MOFGA, also
asked detailed questions about composting and made quite a study of this
five-foot pile of dirt and granite dust, blueberry and other vegetable wastes,
sawdust, rock phosphate, potassium sulfate and horse manure.
Organic production requires organic
rather than synthetic chemical fertilizer, and here Hitchings is abundantly
aided by his wife, Deb Ballam, who keeps five horses for breeding and providing
equestrian therapy for the mentally handicapped. As a bonus, they also provide just the
organic ingredient Hitchings needs for his compost heap.
The group followed a dirt road that
wound onto the barrens where evidence of the past few years of drought was
clearly visible. Some spots that had
been fried by the unusually hot and dry conditions have given way to
grass. Here, David Yarborough,
Extension Blueberry Specialist and Professor of Horticulture had many questions
relating to his fields of expertise - crop management, weed control and field
cover. Organic growing eschews the use
of herbicides and the grass that moved in during the drought has subsided
somewhat according to Hitchings, as a result of his mulching and weeding
efforts. The occasional application of
elemental sulfur has also been found to help lower the PH of the soil and
minimize grasses.
Seanna Annis, Assistant Professor
of Mycology, University of Maine, is an expert in plant pathology, mummyberry,
stem blight and leaf spot diseases and throughout the ramble, she searched for
signs of these problems. One objective
of organic growing is to produce strong plants that are naturally resistant to
disease, but these enemies can spring up anywhere at any time as all farmers
know.
The relative benefits of burning
and mowing were of great interest to all, particularly John Smagula, Professor
of Horticulture at UM and an expert in physiology and culture, crop management
and propagation. Hitchings mows and
burns. He has found that a schedule of
mowing and burning promotes growth and production while contributing to the
control of pest infestation and disease.
Burning vegetable waste is not permitted by federal organic standards
except for burning of diseased plant matter.
Since Hitchings considers burning essential for optimum results in the
cultivation of low bush blueberries, he has created his own trademark brand,
“Eco-Conserve,” which allows burning, but is more restrictive in other respects
than the national standards for organic production. For instance, to qualify as Eco-Conserve
berries, no exotic bees may be introduced into the fields. Instead, the grower must enhance the
environment so local bees will be available to do the job of pollination. Sprays of any kind, organic or otherwise,
are also prohibited, as are “dead animal” fertilizers i.e. those that contain
blood meal and/or bone meal.
The scientists on this survey
discussed insects and fertility at great length. Hitchings’ farm provides good “bee pasture,”
a varied landscape full of the materials bees require in order to thrive. Wild bees need access to water and food, and
sometimes oils, resins, leaves and mud are essential. They also need optimal nest sites,
over-wintering habitat and mating sites in order to sustain a strong population
of pollinators, and flowering plants that are good pollen and nectar resources
for bees must be available from early spring to late summer to insure their
presence in numbers. These flowering
trees, woody shrubs and herbaceous plants serve multiple roles as wind breaks,
floral resources, mating and nesting sites.
It is estimated that only 1% of the
wild blueberries grown in Maine are grown organically. These wild blueberries are already highly
prized and the present demand far exceeds the supply. It is therefore possible for growers to get
more money per quart from their fresh berry customers, as much as 20 to 50%
more in Hitchings’ experience . As the
healthful properties of blueberries become more widely known, it is anticipated
that the demand for organically grown blueberries will increase
exponentially. Since wild blueberries
are smaller than their high-bush cousins, they have more blue skin surface per
quart, making them richer in the antioxidants for which blueberries are
becoming famous. Hitchings has also
compared organically grown wild blueberries with their conventionally grown
brothers and finds the skin of the organic berry just a bit thicker. This makes them easier to handle and far more
flavorful.
It is the goal of The Blueberry
Organic Transition Project, now in its second year operating under a four-year
grant, to add information about organic methods to their already extensive
resources on wild blueberry growing. Go
to www.wildblueberries.maine.edu. for more information on all phases of low
bush blueberry culture and to contact Frank Drummond or any of these
professionals.
Frank Drummond plans to have best
practices information available for those who want to make the transition from
conventional growing methods to organic methods and he’s doing it with the help
of experienced growers like Charlie Hitchings who have been at it for thirty
years.
