How much does lodging affect yield? It depends on when the crop falls.
The evidence is showing up on yield monitors in Ontario’s winter barley fields, and will be showing up in nearby wheat fields next week, says Wheat Pete’s Word host Peter Johnson.
Another thing that is showing up is the impact of compaction, especially in the headlands. Compaction causes roots to stunt and struggle, and the evidence in corn yields is alarming. Will yields recover? What are the plans to reduce compaction? Read on for that discussion and more!

summary
- What happens when a Canadian farmer goes to England and meets a Danish farmer? They talk about the language of Wheat Pete!
- Up to your ankles by July 1? Not a very good week for corn.
- Other corn is kid-high!
- Wheat harvest is in full swing in parts of southern Ontario
- Winter barley yields are good, but soil conditions are poor
- Growing crops are consuming water, but maturing crops are getting the best they can. Don’t delay harvesting.
- Barley ears can become so heavy that the stalks can break off, especially in bad weather.
- Lodging of barley (barley that lodged at the heading stage and barley that lodged early). The yield of barley that lodged early was reduced by almost half.
- Cool, cloudy weather extended the grain filling period, but the cloudiness prevented large kernels from growing.
- The straw yield is huge. The harvest index is not so good (grain/biomass ratio)
- PGRs and herbicides are being used in parts of Western Canada. The leaves are getting bigger!
- The compression of the cape is extremely severe in some areas.
- Corn has turned yellow in some areas, but will turn yellow again once moisture helps the roots break through the compaction.
- Get better tires or switch to trucks and double your headland tiles
- Beware: Tar spots in Michigan, none yet found in Ontario
- Tar spots take 6 weeks
- Late planted corn may be most at risk (before VT timing)
- Scout, Scout, Scout
- Soybean aphids on June 27: Continued monitoring
- Do I apply N to my corn now? When should I sample for nitrates? Interpreting the results. What if it says “Apply 0”? Waist-high corn? Too late?
- During the rapid growth phase, all the nitrates in the soil are absorbed. Nitrate levels will drop to zero. The sooner the better.
- Fungicides for legumes: North Dakota Study Soybean canopy was confirmed to be important: 1 pass: R2.5, 2 passes: fairly early around R1, then 2 days slower, but do take the canopy into account.
- Enlist or Enlist Duo: Remember that volunteer corn management must be a separate pass
- Be careful next year: Growing Enlisted Corn? Resistant to the Jokers
- FHB Index and Harvest Time
- As the wheat matures,
- What about pre-harvest treatment of wheat? It will save you a couple of days and might be worth it, but you need to scout for FHB levels and have a physiologically mature crop ready. Just because you have a low infection rate doesn’t make it worth it.
- Remaining wheat seeds: No need to reprocess, but test for germination
