Monitor bin temperatures to prevent canola spoilage

A recent spike in the instances of heated canola has agronomists warning farmers to monitor their bins.

“If you see a rise in temperature, you need to be pulling out some of that canola and turning it to break up any hot spots as quickly as possible,” said Angela Brackenreed, an agronomist in Manitoba for the Canola Council of Canada.

Heated canola can go unnoticed for days or weeks and the canola council recommends using temperature cables in bins. Producers should also feel and smell the canola as it comes out of the bin.

“Heated canola has a fairly distinct smell to it,” said Brackenreed.

She said the weather can sometimes lead to heated canola, and conditions were not the best this fall.

“A lot of producers found their canola was not maturing and ended up having to, either out of necessity or not knowing, they ended up cutting it a little too early,” she said.

“There was fairly high green seed and fairy high moisture in some cases. Obviously, this can lead to problems in the bin.”

Brackenreed said frost did not help matters.

“It likely had something to do with the seed heating we’re seeing now.”

The exact number of heated canola bushels isn’t available, but Brackenreed said she has seen an influx of calls about heated canola, particularly in Manitoba.

“I have heard some folks at the elevators that they are seeing more samples of heated canola than usual,” she said.

Brackenreed said some elevators have reported receiving so much heated canola that they are unable to accept any more.

“It’s shocked everyone at how quickly the heated seeds did peak.”
