  • Tips for drying tough and damp canola

    Storage-general-other

    With prospects for a lot of tough canola coming off once harvest picks up again, farmers will want a plan for how they’ll handle it. When adding heat to an aeration system, the general recommendation for this method is to increase air temperature to no more than 15-20°C. PAMI storage researcher Joy Agnew notes: “Hotter is NOT always better when using natural air drying with heat. You must match heat addition with your fan capacity. The more cubic feet per minute the fan blows, the more heat you can add.”

  • Put canola on aeration immediately after combining

    Storage-general-other

    Ideally, growers will want to put canola on aeration as soon as it comes off the field. Cooling hot grain within the first 24 hours is important for safe long-term storage. Removing moisture that sweats from all canola — but especially tough canola (10-12% moisture) — is also important. Conditioning achieves both of these steps. […]

  • Blowing cold air through canola bins

    Storage-general-other

    As we exit the winter period of really cold days, growers may wonder whether running fans on cold days to substantially drop the temperature of stored canola is worthwhile? This is not a researched scenario, but we asked grain storage researcher Joy Agnew of PAMI for her thoughts.

  • Time for a mid-winter bin check

    Storage-general-other

    Extended moments of warmer weather in winter can increase air and moisture movement inside bins. Put a priority on canola with moisture above 8% or higher dockage or green seed levels but take a moment to check in on all bins.

  • Storage: Hot canola is at risk

    Storage-general-other

    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 moisture from respiring seed. Even at low moisture, convection currents within the bin could concentrate this moisture. For safe, long-term storage, canola should be conditioned with aeration to less than 8% moisture and cooled to 15°C or less.

  • Insects in spring-harvested canola

    Storage-general-other

    Some farmers harvesting crops this spring have noticed higher numbers of insects in their samples. These are primarily seed-eating carabid beetles and fungus-eating beetles (shown above).

  • Wildlife go for grain bags

    Storage-general-other

    Hungry wildlife may have discovered your grain bags and opened them up for a snack. With the ground still frozen, it may be a good time to empty bags if wildlife damage is evident and spoilage is likely.

  • Check for spoilage

    Storage-general-other

    This is steam coming off canola heating due to high moisture. This was not a welcome sight for the grower.

    Steam coming out of bin doors or snow melting off one bin while remaining on others is a quick clue — but don’t use these as your only indicators! Spoilage usually starts small. Even with temperature cables, start points are not always detected until some of the grain is already damaged.

  • Keep an eye on bags, patch holes

    If leaving bags for the winter, watch them regularly. Feel them for warm temperatures. Probe them if possible. Tape up any holes that may occur due to wildlife or any other damage. Spoilage in bags often starts around holes.
