ABSTRACT
Aeration to cool and improve storage conditions of grain with selected ambient air has been employed successfully under conditions where ambient air is effective during the cold hours of the day or night and in cold weather seasons. However, there are many storage situations where ambient air conditions are not sufficient to cool grain. To control fungi on moist grain, protect grain against mites and insects, control self-heating, preserve the germination capacity and quality of stored grain in warm climates, or when warm grain is stored immediately after harvest, aeration using ambient air may not be sufficient.
