The area traditionally known as the "Corn Belt" in the United States primarily covers regions in the Midwest, particularly states like Iowa, Illinois, and Indiana. This region is characterized by highly productive agricultural lands, ideal for corn production due to its fertile soil and favorable climate. The Corn Belt plays a crucial role in the U.S. economy, supplying a significant portion of the nation's corn, which is used for food, animal feed, and biofuel. This area is vital for supporting the agricultural industry and influencing both local and national economies.
