U.S. corn-soy production concentration evaluated

Both corn and soybean production is relatively concentrated in the Corn Belt, Upper Midwest, parts of the Great Plains and the Mississippi River Region, according to analysis from Gary Schnitkey, ag economist at the University of Illinois.
About half of all U.S. corn is produced in just 220 counties; 75% of U.S. corn production is produced in 456 counties.
Soybean production has about the same concentration as corn: 50% of total U.S. production comes from 256 counties; 75% of total U.S. production comes from 486 counties.
