Combining canola after the ground has frozen can work fairly well, especially for standing crop. In fact, when putting ice and snow covered canola plants through the combine, colder temperatures (-10°C to -20°C) may be better than temperatures around 0°C.

ANY unexpected rise in temperature should be a clear signal that action is required. Once an area starts to warm up, the reaction has started and the canola will probably just get hotter and hotter until spoilage starts. Then spoilage will spread until the whole bin is damaged.
High moisture harvest means steady action around the bins – with oversight of dryers, aeration fans, latches, hatches, augers and trucks. The best advice is to stay out of the bins entirely and keeps all guards and shields in place – just in case.
If N fertilizer is applied in fall, it should be banded, preferably as late as possible – but not too late. Applying into frozen ground or on snow is not a good practice.
Fall is a good time to collect soil for a clubroot DNA test. Information can be used to help with seed and disease management decisions.
Having diversity in canola variety genetics will improve the resilience of the farm over time. The weed management message, “If it works, change it”, should apply to genetics and disease resistance, too.
