FingerLakes Weather In Late Summer Over Hay Crop Stock Photo

Hay is a grass that has been cut, dried, and stored for animal feed. Many different kinds of plants can be used as hay, but in Iowa today, alfalfa and clover are the most common. As Americans moved west onto the Great Plains in the 19th century, they would often use the prairie grasses that were growing there to feed their livestock. Each hay bale is a giant, 700 lb. round bale. They need to dry outside to help prevent spontaneous combustion.
