Canola with high chlorophyll content is less stable in storage, even if the canola is dry and cool. The safest bet is to deliver sooner than later. If that is not an option, proper conditioning and frequent monitoring for heating and spoilage are crucial until it can be delivered.

Other storage risks this fall:
Weed seeds tend to contain more moisture than canola seeds, especially if they are green or immature. These high-moisture seeds may not be enough to elevate overall grain moisture tests, but if these weed seeds congregate in pockets in the bin they can create localized hot spot for spoilage to begin — especially if that canola is also binned hot. Bits of green weed material in the sample increase the risk.
Canola binned hot, even if it has low moisture, low dockage and low green, should still be put on aeration. This will even out the temperature throughout the bin, and help remove some of the moisture from respiring seed. Even at low moisture, air movements within the bin could concentrate this moisture.
Small shriveled canola seed will mean smaller air pockets between seeds in the bin. Smaller particles will increase the resistance to air flow. The fan may need to work harder and longer to cool the entire bulk.
