KEY PRACTICE: Eight percent moisture and cool grain temperatures are best for long-term storage. Ideally, put canola on aeration after harvest to cool it and remove moisture that “sweats” out of the grain. Check stored canola often, and especially when the outside temperature shifts in fall and spring.

After escaping all the yield loss traps in the field, there is one more obstacle to overcome before delivering canola to the elevator: storage. Grain mismanaged in a bin can result in disappointing losses. Paying attention to the moisture and temperature of the grain as well as outdoors is critical to management.
Canola storage was the focus of Joy Agnew’s group at the Prairie Agricultural Machinery Institute (PAMI) this past summer. In collaboration with the Canola Council of Canada (CCC) and the provincial canola grower organizations, she monitored temperatures and relative humidity of three canola bins throughout the summer to determine best management strategies for summer storage. Agnew’s project began in the winter, turning on aeration fans in temperatures below -30°C to freeze the canola. Nine temperature and humidity sensors were inserted into the bins in early June, using long probes for minimal grain disturbance, and monitored until removed.Open the PDF to read the entire research summary from the 2014 Science Issue of Canola Digest
