Three quick questions to help you determine if your aeration fans can do the job.
This map shows a slight probability for higher than average temperatures for September to November 2018.
With prospects for a lot of tough canola coming off once harvest picks up again, farmers will want a plan for how they’ll handle it. When adding heat to an aeration system, the general recommendation for this method is to increase air temperature to no more than 15-20°C. PAMI storage researcher Joy Agnew notes: “Hotter is NOT always better when using natural air drying with heat. You must match heat addition with your fan capacity. The more cubic feet per minute the fan blows, the more heat you can add.”
Aeration fans should be started as soon as the canola covers the floor of the bin, so that immediate cooling can take place. Fans must be operated continuously until the temperature of the canola is near the average outside temperature.
With everything else going on, don’t forget to check bins that already contain harvested canola. Make sure the fans are on. On cool days, consider taking out a few loads to cool them down and break up potential hot spots forming in the central core.
By this time of year, galls may start to break-down. Decaying galls will have a sawdust-like look and texture. If in doubt, send plant samples to a lab.
Despite some wintery weather, we can hope for (and expect) good harvest weeks to come. Don’t rush into pre-winter jobs just yet.
Due to a wet and cool September-October 2016, good harvest weather in November 2016 saved the year for many farmers. Something to keep in mind…according to samples submitted to the CGC Harvest Sample Program, almost all the canola combined in November 2016 graded No.1.

Cool temperatures and a prolonged harvest are making farmers anxious. Are you too stressed? Is stress starting to affect your life? Good people are here to listen.
The ideal swath timing for top yield is when average seed colour change across the field is at least 60% on the main stem. But canola growers may want to reassess that approach based on the following considerations.
