Drill / Planter Clean-Out Procedure

The planter must be thoroughly cleaned out and inspected prior to planting Food Grade and Identity Preserved crops, even when hiring a custom planter. Planter cleaning procedures are as follows:

  • Empty drill/planter boxes and remove any caked-on deposits.
  • Blow out or wash out trapped grain from boxes.
  • Open feed cup gates to drain any trapped grain.
  • Vacuum any trapped grain from the drill box.
  • Use compressed air/turn the fan on to blow out seed tube and seed boots.
  • If air is not available then lightly tap seed tube to free any trapped grain.

  • Attempt to plant Food Grade and Identity Preserved crops before planter is used on other crops.
  • Food Grade and Identity Preserved seed bags should be stored separately from other seed prior to planting.
  • Approved isolation distances for the Food Grade and Identity Preserved crops must be observed.
  • A soybean crop is required to be at least three meters apart from another soybean crop and another pulse crop.
  • Growers should endeavor to leave a minimum one-meter isolation distance between a Food Grade and Identity Preserved field and fields of crops that do not require the three-meter isolation.
  • Grower must have detailed records of: previous crops grown on fields; detailed field maps, written history of previous crops grown, planter cleaning procedure, isolation distances.
