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.
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.)
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.
- Starting to see potash deficiency in more crops — comes back to good residue spread with combines following the same A-B line…
- Soybeans fix N but use more than they fix. Bigger yields = more nitrogen that needs replacing.
- Corn following soybeans requires less nitrogen than corn following corn because it’s not used to break down corn residue.
- Burdock control
