Harvest and Storage

  • Reader question: Does green content go down in the bin?

    Harvest and Storage

    Some researchers found that long-term storage may decrease green seed count slightly, but farmers should not count on a significant improvement in storage – especially if seeds are very dry.

  • Really dry canola. Combining tips

    Harvest and Storage

    With hot and dry conditions, a lot of canola is well below the 10% moisture considered “dry” by grading standards and often below the 8% moisture level considered safe for long-term storage. What can you do?

  • How to reduce costly harvest losses

    Harvest and Storage

    Canola producers can lose up to five bushels or more per acre if the combine isn’t adjusted properly. Here are tips to measure combine losses and make adjustment to limit those losses, putting more canola in the bin and reducing the volunteer canola seedbank in your fields.

  • Storage: Hot canola is at risk

    Harvest and Storage

    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.

  • Fall frost: Swathing and straight combining considerations

    Harvest and Storage

    Pod splitting or pod drop due to tissue damage from the heavy frost usually starts within a day after the frost event. If the canola crop is still sound after that time, growers can probably stick with original plan – whether that be swathing at 60% seed colour change or straight combining.

  • Crop off? Prep for post-harvest jobs

    Harvest and Storage

    Ideal timing for post-harvest jobs varies from right after combining to just before winter. Here is a list of post-harvest field operations and the ideal times to do them.

  • How to reduce costly harvest losses

    Harvest and Storage

    Canola producers can lose 5 bu./ac. or more if the combine isn’t adjusted properly. Here are tips to measure combine losses and make adjustment to limit those losses.

  • Harvesting at 30°C: Cool that canola!

    Harvest and Storage

    Canola storage experts recommend that hot canola be put on aeration for cooling – even if it’s dry. That’s because air currents within the bin can concentrate moisture at the bottom of the central core — creating a possible start point for heating.

  • The right bins for canola

    Harvest and Storage

    Fan capacity is an important consideration in a canola bin. Airflow of 0.1 to 0.2 cfm/bu is needed to condition (cool) a bin of canola. If adding supplemental heat to dry canola, airflow of at least 0.75 cubic feet per minute per bushel is recommended. If fan size is insufficient for the job, fill the bins part way to improve airflow.
