Hemp farming was a
thriving colonial enterprise that played an important role in the genesis of the world's
third largest nation. An essential home industry, hemp was grown in considerable
quantities to supply the cordage and textile needs for the vast farm, forest, fisheries
and mines that now form the economic engine of present-day Canada. Hemp cultivation was
encouraged by French and British colonial administrators to supply European military and
merchant marine needs for almost 400 years. As Canada is favorably situated within
latitudes of the globe most suited to hemp cultivation and blessed with well watered
parcels of fertile soil, it is no surprise that 'Canadian hemp' was the choice for
European purchasing agents seeking the finest quality naval cordage and heavy textiles at
the height of the golden age of sail (1750-1850). This, in turn, made possible a
golden age of Canadian hemp.
The sowing of legal hemp on a former tobacco farm in
southern Ontario has allowed Canada, once more, to join the ranks of hemp growing
nations. In June 1994, farmer Joe Stroebel and his partner Geof Kime owner-operators
of Hempline Inc., sowed 5 varieties of low-THC hemp from Europe under license from the
federal Ministry of Health on 6 acres (2.5 ha) of sandy loam soil. Their pioneering
efforts inspired 12 other Canadian farmers to grow hemp in 4 provinces in 1995.
The pending reforms of Canadian law governing hemp will
soon enable other farmers across Canada to sow hemp without the cumbersome paperwork
currently required. Legislation dating from 1938 is being revised to advance
progress for the agricultural sector while meeting our obligations to the international
community. Canada is expected to release a comprehensive new drug policy in 1996
that may allow exceptions for the cultivation of hemp. However, Cannabis continues
to be a controlled crop under present day Canadian law. There is no distinction made
between marijuana and hemp. As the entire Cannabis
plant, its derivatives and cellulose products
(excluding sterile seed for canaries) are technically illegal, Hempline Inc. was unable to
obtain reliable information concerning cultivation practices or methods from Canadian
government sources who maintain no files on illicit crops. In order for their pilot
project to get off the ground, Hempline Inc. turned to private-citizen hemp-activist
groups such as H.E.M.P. Canada and the Hemp Futures Study Group, where they found
both data and much needed encouragement. Prominent Canadian lawyer Allan Young helped to
navigate them through an ocean of bureaucratic reluctance and legislative red tape to the
point where they were ready to submit their application for the first Canadian hemp
licenses in three generations. There are, of course, no grants or subsidies
available for growing hemp in Canada, and Hempline Inc. was obliged to pay its own way,
including police surveillance fees.
When Hempline's application to grow hemp began to take
shape in early 1993, they were aware that the Federal government did not welcome their
proposal and would take a strictly business stance in the matter. After careful
evaluation and consultation with the Ministry of Health, crop specialists and law
enforcement agencies (under who's jurisdiction the Cannabis plant falls),
their initial application to grow hemp was seriously considered. There was no review
body in place to process hemp applications and there was no precedent in living memory to
base criteria for granting licenses. Special arrangements were required for
monitoring the fields by federal and provincial police. This was deemed necessary as
Royal Canadian Police experience with a government research project growing high THC Cannabis in
1971 that was a target for numerous thefts. Their sense of caution is therefore
comprehensible, but apparently, they do not understand the non-psychoactive aspects of the
industrial hemp plant.
Currently, Canadian hemp growers must have a license to
cultivate hemp, a license to distribute Cannabis
products, a license to import
"narcotics" (hemp seed) and a license to import agricultural seed before they
can sow. Under the terms of their license, Hempline Inc. was required to obtain a
separate permit for each variety of hemp seed they imported, as well as secure additional
permits to cultivate Cannabis and distribute the harvest to certified "end users"
and still another license to export their hemp across international borders into the
United States for special testing. It is hoped that formalities will be streamlined
in the future as this application process, monitoring, and security exceed the time, cost
and effort required to actually grow the hemp crop.
Law enforcement officers monitored every aspect of
Hempline's project from importation of seed to delivery of the dried stalks to the end
user. Samples of growing hemp were regularly gathered for analysis during the summer
of 1994 to determine if the levels of cannabinoids were within limits set by the Ministry
of Health Department of Dangerous Drugs guidelines. Low levels of THC were expected
and found. There were no instances of theft or permit violation. Because of
this, surveillance during the 1995 crop was relaxed somewhat.
Hempline Inc. endured as their first application was
regularly sent back to them for revision. This caused a six week delay from their
optimal sowing date of mid-April 1994. In spite of late sowing on June 1,
germination was uniform and the fields were full. Traditional methods of soil
preparation were employed and seeds were sown with a close spacing of 2-3 inches in rows
6-9 inches apart. A modified seed drill placed seed at a density of about 250
seeds/m2. Fertilizer and lime were applied prior to seeding to bring
fertility and pH levels within ranges suitable for hemp. The plants grew 2-3 inches
per day during one of the hottest and driest summers of the century. They reached an
average height of over 12 feet (4.0 m) in only 75 days without irrigation.
Hempline Inc. harvested their second successful 18 acre
(7.5 ha) crop of two Ukrainian varieties (YuSO11, YuSO13) this past summer divided between
their original Tillsenburg plot, a second location near London, Ontario and a third
smaller field. The fields were harvested using a conventional sickle bar attachment
to a standard farm tractor as the male plants began to shed their pollen and well before
the female flowers reach maturity. The license did not allow seed to form. The
yield and quality were good ranging from about 2.0-3.5 tons of dried stalk per acre
(5.0-8.5 tons/ha). This approximates modern hemp yields in Europe and Asia.
Further field trials may well lead to an increase in both fiber quality and yield.
The hemp industry is sorely lacking machinery that will
cut and bale hemp in one pass through the field. The design and development of such
machines will make the hemp harvest advance beyond existing limits of efficiency.
Designers could begin by copying the principles used in turn-of-the-century equipment
exhibited in museums and the more modern equipment from Europe.
Hempline Inc. sent the major portion of their initial
harvest to an Oregon Forestry product research laboratory where it was ground up, mixed
with a binder and processed into sheets of 1/2 inch (1.3 cm) wallboard. This medium
density building material was found to meet or surpass industry standards of strength and
finish. Other experiments with the first hemp crop produced fist-sized
super-compressed pellets for low smoke/high calorie fuel suitable for urban institutional
heating plants. Additional experiments are still in progress and more experiments
are planned for the output of the 1995 crop.
The 1995 growing season included additional
participants. Gordon Schiefele, a research crop specialist with the Ontario Ministry
of Agriculture and Food, performed a small (400 m2) planting density trial at Ridgetown, Ontario. The
extrapolated yield was 2.7-4.8 tons/acre (6.5-12.0 tons/ha) which is high and probably
results from the small trial size. Some ripe seed was also produced. Dr. A.
Slinkard from the Crop Development Centre of the University of Saskatchewan also sowed
three varieties on small (5 m2) test plots.
Dr. Joe Moes, a new crops agronomist with the Manitoba
Department of Agriculture, along with the Manitoba Hemp Alliance sowed 6 varieties on 10.5
acres (4.2 ha) in four locations across Manitoba. Their yields ranged from 1.8-3.1
tons/acre (4.5-7.7 tons/ha). Fiona Briody of the Northwest Peat and Crop Company
grew three varieties on 2.5 acres (1.0 ha) near Barhead, Alberta. Other small plots
were also grown in Alberta and Ontario. In British Columbia one small farm of
supposedly "low THC" hemp was raided and the grower arrested. No hemp
cultivation licenses were issued in British Columbia.
It is anticipated that the Canadian government will
issue many more hemp licenses in 1996 than in 1995. The arrival of hemp is
encouraging to Canadian farmers facing declining farm income. As food imports from
the USA displace such staple crops as cereals and oilseed from Canadian agricultural
strategies, hemp looks very attractive to the farmer seeking new opportunities for the
next century. Canadian large scale farming is readily transferable to growing hemp
on a scale that cannot be easily matched in Europe. Access to the huge American
market is also nearby. We remain on friendly terms with our trading partners since
joining the North American Free Trade Agreement (NAFTA), whose collective policies favors
North American grown fiber and penalizes foreign imports. No cotton can be grown in
Canada, yet Canadians consume many millions of dollars worth of cotton goods each year
grown primarily in the United States and Mexico. There is reason to believe that the
United States will not allow Cannabis cultivation within this decade, as her trade and industry
policies are wedded to the criteria dictated by its "war on drugs". All
the better for Canada to be the first and only continental source of hemp. This
should be a potent motive for the Canadian farmers to offer the most reliable and highest
quality hemp to the biggest market the world has ever known. The 21st century may
well see hemp fiber from Canadian farmers competing vigorously with cotton.
