Corn Quality Patterns in U.S. Markets
Data on U.S. corn quality were summarized by geographic region and market location. There were significant variations in composition (protein, oil, starch) within and across regions. Intraregional composition differences are economically significant at the first handler level, but one uncontrolled commingling will eliminate any usable differences. Physical quality, as measured by U.S. grade factors, did not show regional patterns.
