Walls may need to be reinforced with cables or braces. Corn exerts a force on a wall of about 23 pounds per foot of grain depth, so with corn 6 feet deep on the wall, the force pushing out at the bottom of the wall is about 138 pounds per square foot. Buildings used for storage should be well drained. Cover floors with plastic to prevent moisture migrating from the soil or through cracks in concrete floors into the grain. Cooling the corn with aeration is extremely important for storage.
Cool temperatures minimize mold growth, limit moisture migration, and control insects.
Provide for air to enter and exit the building for aeration. Corn must be dry when placed into storage. It is nearly impossible to dry corn in temporary storage. If you must pile the corn outside on the ground, drainage is crucial. The pile should be on high ground and the earth crowned under the pile.
