Hemp History
Origins in central Asia
Used widely across Europe and Asia since Neolithic times
First cultivated as far back as 8000BC
Used for clothes, rope, shoes, and early paper in China
Referenced in early Jewish records from the 2nd century
Used as food ingredients in medieval Europe
Later cultivation focused on fiber
Brought to the Americas by the Spanish in the 16th century with great success in Chile
Later Native Americans and Puritans are recorded cultivating hemp in the mid 17th century

Hemp in Modern Times
Widely produced in the US until the Marihuana Tax Act of 1937 is introduced by FDR
Lifted during WWII to supply fiber for the military to manufacture uniforms, canvas, and rope – 36,000ac
For the rest of the 20th century hemp production occurs almost exclusively in Europe and Asia – Primarily Russia and later China
1971: the UK begins decriminalization
1998: Australia and Canada start issuing production permits
1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state level, but federally, industrial hemp is still illegal to grow in the U.S.
2018: President Trump signs The Hemp Farming Act of 2018 into law

Modern Hemp Uses
![Page 10: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/10.jpg)
DON’T GROW HEMP!!!
![Page 11: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/11.jpg)
Seeding
28-30 pounds per acre
9-12 plants per square foot
Seed shallow – ½ to 1 inch
Warm soil-above 50F
Ensure adequate packing but avoid crusting
Use low air speeds to avoid cracking and residue build-up
Spacing should be further apart to promote branching for grain production
Tighter spacing will encourage taller plants and less branching for better fiber quality
Early seeding will produce more plant growth
Late May to early June
![Page 12: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/12.jpg)
Fertility
Fertilizer rates are between high yielding wheat and corn
Nitrogen application rates~120lb/ac
Trials show benefit up to 200lb/ac – more important for grain yield
Phosphate applications between 25-30lb/ac
Higher rates will be required under higher production systems
Potassium levels should be monitored to ensure adequate supply
250ppm or higher
Sulfur deficiency could limit grain yield and oil content
![Page 13: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/13.jpg)
Weed Management
Pre-emergence burn off with glyphosate Rapid plant growth results high competitiveness, 12” of growth in the first month Limited registered herbicides in Canada
Edge- Ethalfluralin, AssureII- Quizalofop
Virginia Tech herbicide tolerance studies Herbicides flumioxazin, clorimuron, pendimethalin, metribuzin, and linuron appear to be
suitable pre-emergent herbicides for industrial hemp grain or dual-purpose production.
Herbicides clorimuron, pendimethalin, bromoxynil, quizalofop, sethoxydim, and halosulfuron appear to be suitable post-emergent herbicides for industrial hemp grain or dual-purpose production.1
Verify with processor before using any pesticide

![Page 22: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/22.jpg)
Grain Yield and Returns
Grain yield 400-1800 lb/ac
600-1200 lb/ac is typical
Prices are volatile
50-65 cents per pound
Organic is normally double
Gross return expected to be $400-600/ac
![Page 23: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/23.jpg)
Fiber Production
Taller varieties
Higher plant densities reduce branching then hurd
Reduced fertility rates
Know your market
Hurd- building materials, mulch, paper
Bast fibers- Textiles and industrial products
Longer stalks are generally preferred
60 days from planting
Double crop potential?
Sickle is ideal
Retting – at least 30 days
![Page 24: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/24.jpg)
Fiber Yield and Returns
2000 – 10,000lb/ac
6-11 cents per pound
About $300/ac gross return
Transportation cost
Lack of universal quality standards
Contamination
Non-hemp plants
Plastics
Stones
![Page 25: Industrial Hemp Production...1998: Australia and Canada start issuing production permits 1999: North Dakota, Minnesota, and Hawaii legalize the growing of industrial hemp at state](https://reader036.fdocuments.in/reader036/viewer/2022071215/6044c2993f3b025c3427e8de/html5/thumbnails/25.jpg)
CBD
Still a regulatory nightmare in most, if not all, jurisdictions
Market size vs. hype?
Extracted from female flowers
Unpollinated CBD content is about 15%
Pollinated flowers drop to 1.5%
Potential to extract from harvest residue High volume, low yield
500lb/ac
$100/lb???
Proceed with caution
