Industrial Hemp Production Tips & Tricks

The following information is a list of suggestions only. Agronomic decisions should be made on a case-by-case basis with your farm’s agronomist.


Seeding

  • Seed into ground free of chemical residue such as Odyssey, Avadex, Pursuit. Canola stubble works well.
  • Seeding date target: May 15th-June 5th. The soil temperature should be 8-10 degrees Celsius or above
  • Grain production seeding rate: 22-25 lbs/acre
  • Fibre production seeding rate: 35-45 lbs/acre
  • Seeding depth: 1/2" - 1"
  • Use minimum air flow on your air seeder to avoid seed cracking in manifolds
  • Calibration of all seeding equipment is essential
  • Fertilizing Rates:
    • 70 to 90 lb. actual Nitrogen
    • 35 to 40 lb. actual Phosphate
    • Potash and Sulfur as required as per soil testing


Grain Harvest

  • Moisture target to begin harvesting: 15% – 25%
  • Begin to dry grain within 4 hours of harvest or sooner. Dry to 9% for storage.
  • Watch for heating, or use a full floor aeration bin with a large fan. The depth of the grain in bin should be about 4-5 ft.
  • Handle hemp grain with the auger full and at a slow speed (similar to handling peas, beans, etc.) or use a conveyor
  • Straight cut the crop as high as is required to harvest seed from stalk, without taking in more fibre than necessary
  • Combine settings depend on field conditions and the type of combine. Start with canola settings and adjust from there.
  • Combine Modification:
    • Narrow the feeder house by placing plates on each side of feeder
    • Observe all places any wrapping could occur and address the problem promptly. Temporary tin shields may be useful. PVC shields on the driveshaft may also be useful.
    • Other modifications may be required depending on the type of combine being used. Use caution. Check often for wrapping.

Fibre Harvest

Cutting:
  • Machines used for cutting: self-propelled swather or haybine
  • 16-18 ft swath maximum (swath must fit baler)
  • Cutting height: as close to the ground as possible
  • Cutting pattern (behind combine): Opposite to combine travel so as to pick up fibre in tracks a give the knife a chance to clear
  • Fibre only crops: Cut after pollination (flowering) – 50% seed set; should be cut before viable seeds are present

Baling and Bale Storage:

  • Soft-core and hard core balers have both proven to work
  • Address any problems of wrapping by covering the area with tin, canvas, or whatever works in the particular situation
  • For highest price potential bales must be at 15% moisture or lower
  • Bales must be kept dry and preferably stored under cover
  • Do NOT rake, as stones may be picked up and embedded in the swath
