Following are some general BMPs when it comes to late seeding, broadcast seeding and general crop solutions with a late spring. WE KNOW THIS – Broadcasting generally produces lower yields than seeding with a drill.



  • Seeding after the middle of June is getting late for canola
  • Consider switching to an earlier maturing variety
  • Increase seeding rate to 7-8 plant/ft2 to compensate for non-uniform seed depth
  • Seed shallow – canola seeded at ½ inch can emerge 3-4 days earlier than canola seeded deeper
  • Consider 85-95% of recommended N – helps canola from staying too long in the vegetative stage
  • Seed place as much P as possible for pop up effect



  • Requires good seed to soil contact in a firm seed bed
  • Avoid fields with a thick layer of thatch
  • Cultivating ahead of the floater could just make seed bed worse – clumpy, crusty
  • A loose, fluffy seed bed can also cause issues with seeding depth
  • Increase seeding rate to 7-8 plant/ft2 to compensate for non-uniform seed depth
  • Harrow after the floater leaves the field at a right angle to the floater pattern – this will help spread out seed and fertilizer
  • Packing after seeding could improve success
  • RULE OF THUMB: If it is too wet to harrow a field – it is too wet to broadcast


  • Starter P is not enough when broadcasting – apply full rate to help with seed to prill proximity
  • Use Jumpstart on canola seed to provide another P source and emergence boost
  • Broadcast P is only half as efficient as banded.
    • Treating with Jumpstart can help solubilize soil P
    • Apply Yield+ from Xcite Bio at herbicide timing – can provide 30% more P to crops
  • If mixing fertilizer and seed – broadcast within a few days – fertilizer is abrasive and could reduce seed viability

Post Seed / Pre-Emerg Herbicide

  • Seeds on the surface are highly vulnerable to herbicide
  • Do not apply post-seed/pre-emergence glyphosate on Liberty Link and Clearfield canola varieties that have been broadcast and remain on the soil surface
  • Roundup Ready varieties can tolerate glyphosate at this early stage

Weed Control – Late & Broadcast

  • IMPORTANT to control weeds pre seed
  • Canola on canola –
    • Need to control volunteers
    • Currently researching what products can be used with broadcasting
    • Be vigilant scouting for flea beetles, cutworms and blackleg

Disease Control – Late & Broadcast

  • With our current moisture level we may be at risk for Sclerotinia.

**NOTE: Seeding canola with a plane or helicopter should only be considered as a last resort. Canola is light and will not penetrate the soil when seeded from the air


Broadcasting wheat is the last resort. This will not result in a good stand BUT is a better option than chem fallow!


  • Moving into June is getting late for wheat
  • Increase seeding rates 1% for each day planting is delayed to a maximum population of 38-40plant/ft2. This helps prevent tillers that delay maturity.
  • Seed shallow – 1 inch
  • Take note of your variety and it’s days to maturity


  • Wheat, barley, oat, triticale, rye have a different root system than canola or soybean
  • If possible, run over the broadcast wheat with some form of tillage – if it sits on top of the ground it is subject to both getting adequate moisture to germinate, and wind injury before the 3 leaf stage (when it starts making nodal roots)


  • Consider lowering N – should not be over 110 lbs if seeding into June
  • Seed place as much P as possible for pop up effect
  • BROADCASTING P is only half as efficient as banded
    • Treating with Bionic can help solubilize soil P
    • Apply Yield+ from Xcite Bio at herbicide timing – can provide 30% more P to crops


  • Need to burn off land if broadcasting. Looking into if any products can’t be used in a broadcast situation


  • Late seeded wheat will be prone to Fusarium Head Blight – plan a fungicide application
  • Wheat Midge will also be a problem as late seeded wheat will be susceptible


2022 Crop Insurance Deadlines and Crop Maturity

Seeding Dates

  • Seeding up to June 20 – will need frost free days until Sept 20.

Switching Crops

  • Barley/Peas have shorter maturities but both are affected by July heat.
  • Oats can be longer in maturity – watch variety. Seeding later than June 10 for seed oats is getting late. Oats for forage is okay at this date.
  • Soybeans seeded in June is not a good practice. Need a plant developed by summer solstice – June 21. Soybeans will also need a long backend frost free. Longer than wheat or canola.

Top Dressing

We have AMPLE time to dribble band or float Nitrogen!

  • Up to 5 leaf for wheat
  • Up to early bolt for canola
  • OR within 5 weeks of crop emergence

ALL top dressed nitrogen will need to be stabilized. See the Stabilizer Better/Best list!


  • Canola is a very plastic plant – meaning it can deal with many stresses better than other crops
  • We are in a good radius for crushers that can deal with canola green seed in the event of a frost
  • Avoid the use of Plant Growth Regulators like Manipulator and Moddus – they extend crop maturity!
  • Wet land can get wetter without crop establishment as there is no growth to draw out moisture
  • Maturity of the crop will be more variable with broadcast – timing of fungicides will be more of a challenge
