Wheat Pete’s Word, Dec 6: Mindset matters, fungicide ROI, and investing in soil organic matter

(Laura Sytnyk/supplied)

Hello, December!

On this week’s episode of Wheat Pete’s Word, host Peter Johnson gets further in to the soil organic matter discussion, including the long-term legacy of manure applications, talks sulphur management, and compares some findings on the ROI on fungicide on corn.

  • Too much stress is no good, but a little stress is actually good for you — so long as you understand the value of it
  • Mindset matters
  • Kevin (@CanadianCowMan) is under an atmospheric river out in B.C. Yikes!
  • Yesterday was World Soil Day
  • Potato farmers have challenges, but also working on some solutions, i.e. using cover crops, reducing tillage
  • 930,000 acres of winter wheat estimated for ’24 harvest
  • Soybean data is in!
  • GoSoybean.net
  • 93 bu/ac for Ridgetown
  • Question: Biosolids (treated) spread on snow on frozen ground…. NO. Hard stop.
  • It will not end up where you want it
  • (Snow over thawed ground? That’s a different conversation)
  • Fungicides, Essex County, and sandy soil
  • Soil type matters for high yield potential
  • But, unsprayed corn in tar spot areas got hit HARD
  • Outside the tar spot area, average about 14 bu/ac advantage and nice DON suppression. Likely some Northern corn leaf blight protection and stay-green impact
  • A load of corn with 50 ppm on three different tests….accurate? They top out at 50
  • Still not as bad as 2018, avg is 2.9 ppm vs 2018 over 7 ppm on average
  • Two plots, same hybrids, 2 days of planting dates difference… larger spread between good/bad hybrids
  • Organic matter discussion!
  • Manure only for many years. Soil health, soil organic matter pays even in years your don’t fertilizer
  • 20 years of beef manure pays dividends for decades (based on super long term data)
  • A little P, K and Magnesium plus some N, triples the yield vs a no-fert check, but still half of what is possible
  • Can you build sulphur levels? Elemental (fine) vs. sulphate — smaller pellets speeds up biological activity?
  • Here’s a link to more on building S levels
  • High phos soil test on corn, two reps when looking at starter fert. On a high soil test, there is a small advantage, but not as much if P levels were low, overall
