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


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
