Why wouldn't everyone have cut down their corn yet? Why do people not pick the ears but let them completely dry out on the stalks? Some other farmers in our area still have fields of dried out corn.
That's probably feed corn for livestock. They let it dry on the stalk and then chop it and blow it into a silo to make silage for cows. The corn ferments in the silo, it adds protein to the corn, and makes quality feed for milk cows.
