It’s a special edition of the Word this week, as Peter Johnson, our resident agronomist at RealAgriculture, hosted his weekly agronomy discussion live at Canada’s Outdoor Farm Show on Tuesday. It was a chance to have Wheat Pete answer your questions in-person, whether talking about his first-love crop, fall weed control or the nutrients in soybean and corn residue.
Watch, listen or download below! And of course, if you have a question for Peter for next week, call 1-888-746-3311, send him a tweet (@wheatpete), or email him at [email protected].
And if you’re at the show, and missed the live taping on Tuesday, the Wildman will be back at the PRIDE Seeds booth at 1 p.m. Thursday for another hour-long Q and A session (which we also plan to post here on RealAg.)

Highlights:
Big Yields = Better Soils?
- Big yields put more organic matter back into the soil.
- Soybeans don’t leave much residue.
- Need to spread residue out evenly for uniform growing conditions for subsequent crop.
Fall Weed Control
- Fall weed control after soybeans — not spraying herbicides in fall is one of the biggest missed opportunities in Ontario ag. Get better control with glyphosate on weeds like sow thistle and fleabane.
Potash Deficiency
- Starting to see potash deficiency in more crops — comes back to good residue spread with combines following the same A-B line…
Soybeans
- Soybeans fix N but use more than they fix. Bigger yields = more nitrogen that needs replacing.
And more…
- Corn following soybeans requires less nitrogen than corn following corn because it’s not used to break down corn residue.
- Burdock control
