History suggests total corn, soybean, and wheat acres in the state of Illinois will range between 20 and 20.7 million acres in 2021. Current economic conditions suggest a shift from corn to soybeans. If this does occur, one would expect all areas of the state to make roughly the same proportional change. Historic relationships likely will persist and northern Illinois will grow more corn than soybeans while southern Illinois will grow more soybeans than corn.
