Forecasts for freezing or near-freezing temperatures when late-planted fields of corn are not yet mature (i.e., not yet at kernel black layer) are naturally concerning to farmers and the grain markets. Learn about the consequences for grain yield, grain moisture, and harvestability of immature corn damaged by frost or freeze events from Purdue University.

Frost damage tends to be worse in low areas where cold dense air settles and in fields where high levels of surface residue coverage limit heat transfer from soil.
