Spring Grain Drying and Storage Management Kenneth Hellevang, Ph.D., P.E.
March 6, 2010
The storability of grain depends on the grain quality, moisture content, and temperature. Grain moisture content must decrease as grain temperature increases to safely store grain. For example, the allowable storage time of 22 percent moisture corn is about 190 days at 30 degrees, 60 days at 40 degrees, and only 30 days at 50 degrees. Therefore, as stored grain temperature increases the grain moisture content must decrease for safe storage. Find out more...

*Based on 0.5% maximum dry matter loss?calculated on the basis of USDA research at IowaStateUniversity.Corresponds to one grade number loss; 2-3% pts in damaged seeds
Soybeans approximated at 2% lower moisture than corn.
