Grain quality will not improve during storage. At best, initial quality can only be maintained. To help assure that only high-quality grain goes into storage, the following is recommended:
- Clean around the storage site. Remove any old grain, grass, weeds, and other debris.
- Remove all traces of old grain from the storage and harvesting and handling equipment.
- Properly adjust the combine (harvesting, threshing and handling equipment) to minimize grain damage.
- Clean the grain as it is put into the storage, preferably using a rotating grain cleaner.
- Cool the grain to the prevailing outside air temperature (that most usually occurs) as soon as it is put into the storage.
