Temperatures are rising in some canola bins across the Prairies.

Angela Brackenreed of the Canola Council of Canada says she's heard some cases in Manitoba, but doesn't think it's very widespread. Nonetheless, she thinks it's still a good idea to check grain bins, especially heading into winter when the temperature outside the bin could be lower than the temperature inside the bin.

"What you tend to see happen with air movement is that cold air will sink on the outside wall, and the warm air moves up the middle core. Then where you tend to see that first kind of moisture zone starting to occur is right at that top central core of the bin," she says. "The reason I bring that up is you can't just open the door at the bottom and probe in there. You really need to be checking in a few spots, and really ideally take a load out and actually turn the bin."

The Canola Council of Canada says there are many factors that can cause canola temperatures to go up, such as a hot harvest in August or green weed and canola seeds. Brackenreed says this year, adverse weather is to likely blame for heated canola in Alberta specifically, causing uneven crop conditions with potentially higher moisture. She says it's also harder to dry down the bulk when harvested later in the season.

Rising temperatures in canola can cause heat damage to seed, which would mean a big downgrade in quality.
