Wheat Pete’s Word, Feb 21: Product residue, carbon to nitrogen ratio, split-app N, and powerful ground

When you think about managing crop residue breakdown, do you think about the carbon-to-nitrogen ratio of the residue? If not, it might be time to do so, as genetic advancements in corn, for example, has actually made it somewhat harder for stalks to breakdown.

That’s just one discussion in this week’s episode of Wheat Pete’s Word, but there are plenty more. Listen now or download for later and hear about frosts seeding vs. drilling clover, when potash does best for corn, product residues in oats, and why right now is a sweet time of year.

SUMMARY

  • Maple syrup season is getting rolling in Ontario’s south — tapping this early IS early
  • Mild winter in the south, for sure, and further south in to the states too. No N too early!
  • Did wheat break dormancy?
  • Big shot of N when wheat greens up is a need
  • Get the planter rolling? Not so fast!
  • It’s all about rainfall, and frost
  • Environmental working group published a report on CCC (used on wheat, barley, and oats in some parts of the world), i.e. Manipulator
  • The dose makes the poison, and because we can find it, does that make it a hazard?
  • Detection levels are a concern, nonetheless, as a public perception issue
  • Crop Protection Network website, seed treatments on corn and soy. Foliar to on-seed?
  • Frost seeding clover: spin it on vs drilling
  • There can be an advantage if you’re late but earlier is better and spin it on
  • Drill can damage the wheat
  • Alfalfa doesn’t thrive under wheat
  • Hay crops love N
  • How powerful is your ground?
  • Lodging risks!
  • When should you soil test established hay ground? Be consistent!
  • Cardboard, sawdust, straw — C:N of cardboard 400:1, sawdust 200:1
  • Wheat straw is generally 80:1 up to 150:1
  • Corn stover now has a higher ration 55:1 vs 70:1 now
  • That’s because modern hybrids are better at taking nitrogen out of the stalk and putting it in to the grain
  • Makes a difference for bedding, but really makes a difference on corn on corn
  • It’s going to take an extra 20 or 30 pounds of N to break it down!
  • Quality vs yield in corn
  • Potash in the fall vs spring — which one matters more?
