Welcome to the Iowa Grain Quality Initiative!


The mission of the Iowa Grain Quality Initiative is to create knowledge and provide information that will improve the efficiency of traditional commodity grain markets and will assist emerging markets for user-specific grains.

The Grain Storage Team is an Iowa State University Extension team of ag engineers and ag economists which have developed grain storage training tools which discuss grain quality.

The team has developed new training tools and updated some previous economic tools. The new tools are listed on the Grain Storage page with supporting information.

    • Recent cold temperatures in Iowa created instances of frost damage to immature crops in Northern Iowa, and more widespread damage in Minnesota. The degree of loss depends on the closeness to maturity and the length of time below freezing. In Iowa, the damage was mostly to grain quality rather than quantity. The bulletin   PM1635 Frost Damage to Corn and Soybeans explains the likely results of early frost. Proper handling and management procedures to minimize the impact of early frost on storage and marketing are explained.
