Wheat Pete's Word, Feb 15: The power of potash, undead oats, rotation, and Canada's Ag day


It’s Canada’s Ag Day, and it’s time to celebrate the food and farmers you love. How are you celebrating?

That’s how Peter “Wheat Pete” Johnson kicks off this week’s Wheat Pete’s Word before diving in to the topics and questions of the week, including if cover crops are really going to be dead come spring, sulphur management, and final corn and soybean yields in ’22.

Have a question you’d like Johnson to address or some yield results to send in? Disagree with something he’s said? Leave him a message at 1-888-746-3311, send him a tweet (@wheatpete), or email him at [email protected].


  • Happy Canada’s Ag Day!
  • Canada is the 5th largest agriculture food exporter in the world — our number one crop is canola!
  • Check out our little video here
  • Maple syrup season has begun in the way south of Ontario. It’s the sweetest time of year
  •  What does the syrup season mean for the growing season? Hmmm
  • Shameless self-promo: Thorndale Dinner Theatre the next few weekends, and Wheat Pete will be in the play!
  • Corn wagers: 184 bu/ac vs 186 bu/ac. Ontario average hit 103 per cent of average, even with the drought
  • Soybeans at 48 bu/ac 102 per cent of average
  • Elgin County won with best results for the year at 205 bu/ac corn and 58 bu/ac soybean averages
  • The east did incredibly well! (Editor’s note: that’s Ottawa and east/south of Ottawa, not Belleville, FYI)
  • Edible bean report: Cranberries were under average, kidneys did 114 per cent of long-term average
  • Dean and Dan sent questions about oat cover crops right now — some were sprayed in the fall, but will they survive?
  • They might! Check out The Agronomists February 27 to talk all about spring management of cover crops
  • Dig some up, let them warm up and see if they grow some new white roots
  • Oh my gosh, 32 years of continuous years soybeans….what what what
  • Split it — 28 bu/acre vs. 40 bu/ac with just ONE year out of bean. Wow
  • Glyphosate resistant fleabane loooovess continues beans
  • Rotation is the 5th R (Read more here)
  • Sugar beets after beans vs beets after wheat and cover crops bought some yield
  • The power of potash! Not enough K? You get less out of the N
  • Shaun Casteel: sulphur on soybeans. Some cool discussions. Early beans, sandy soil needs S
  • It’s needed at reproductive stages
  • KMag or SulphaMag didn’t bring us much to the table as other sulphur sources
  • Spring K reduced yield. Why? Excluder vs includers on varieties
  • Read more on the chloride here
  • Soil DNA and rock phosphate: Does high soil test P mean it’s available? Sodium bicarb can do that job, too, that’s why we use it in a soil test
