Grain Storage
Average grain temperature should be above 35°F in the winter and below 65°F in the summer. Always try
to keep the grain within 10°F-15°F of the average monthly outside temperature. This means grain may
need to be aerated on warm days during the winter to stay above 35°F when freezing temperatures are
predominate. During the summer it may be necessary to aerate the grain on cool nights, so the 65°F
temperature is not exceeded during the hot days of summer.
If the grain is to be stored more than 1 year, it has to be recooled the following fall and winter, repeating
the process as long as the grain is in storage. Frequent and regular inspection (at least weekly during
fall and spring) is the best prevention against grain spoilage.
