Warm Winter Days Can Increase Storage Risk

Moisture migration in a canola bin peaks when the temperature difference between inside and outside the bin is high. For example, if canola in the bin is -10C and the temperature outside is -30C, air movement inside the bin will be more active than when the difference is smaller. Same if canola in the bin is -20C and the outside air warms up for a week, which often happens this time of year.

 

Sometimes a quick scan of the bin roofs can provide a indicator. If most bins have snow on them, while some do not, that could be a sign that there is variation between bin temperatures. The best way to check is with temperature cables, or by removing at least one third of the canola in a bin. Probes can also work to check the top or bottom of the central core, which is where heating is most likely to begin. However, heating can also start in pockets of dockage along bin walls — where probes cannot reach.

For over two decades, Dr. Mitloehner has been at the forefront of research on how animal agriculture affects our air and our climate. With deep expertise in emissions and volatile organic compounds, his work initially focused on air quality in regions like California’s Central Valley—home to both the nation’s richest agricultural output and some of its poorest air quality.

In recent years, methane has taken center stage in climate discourse—not just scientifically, but politically. Once a topic reserved for technical discussions about manure management and feed efficiency, it has become a flashpoint in debates over sustainability, regulation, and even the legitimacy of livestock farming itself.
