Corteva summarizes the 2022 drought, which spread east across the Corn Belt by late October, when 71% of corn area was in drought. Iowa averaged 202 bu/acre and Illinois 215 bu/acre, while Nebraska yields fell 13% and Kansas 17% from 2021.
The drought's late timing spared the eastern Corn Belt yields but hit the western Plains hard, reinforcing the tight-supply picture for corn and related feed ingredients.
