A recent canola bag storage study concluded that:
—Harvest bags are best used as a short term storage solution under Prairie conditions.
—Dry canola (less than or equal to 10% moisture) can be stored for up to eight months and 12% moisture content canola can be stored for up to five months without any significant change in quality or grade using harvest bags during autumn and winter.
—Canola above 12% moisture content should be stored only for three to four weeks in the harvest bags to avoid quality and quantity losses.
Cold winter temperatures will increase storage safety. The smaller diameter of the grain bag may also mean that grain cools faster than in a bin, and that hot spots may be localized — as long as you keep an eye on the bags through the storage period.
