Check Grain Bins Regularly in Winter

Now that grain is stored, it’s important to check grain bins regularly. Growers need to monitor stored grain carefully throughout the storage period.  Routine checks should be made at least every two weeks – even in winter months, say DuPont Pioneer experts.

A regular check of bins allows growers to assess the condition of grain. It also provides the opportunity to catch emerging problems before they result in spoiled grain.
Here are some tips for monitoring bins:

  • Smell the exhaust to detect musty odors that indicate molds are developing.
  • Check the grain surface for crusting, wet areas and molds, as well as insect and rodent activity.
  • Check grain temperature and moisture. “In-bin” electronic probes, which are becoming more common, allow growers to monitor these properties continuously.
  • Probe the grain mass to check for “hot spots,” molds and insects.
  • Check inside the roof of the building for condensation and leaks.
  • Make sure the building exterior is well-drained, weather-tight, rodent-proof and not physically damaged by the forces of the grain. 

If you detect any problems, correct them immediately. If necessary move the grain to a different storage facility.
