Corn is defined as a grain crop that grows on a stalk. The kernels of corn grow in rows on each ear. Most people are familiar with the fresh corn that can be found in the produce department of the local grocery store.
The grain type corn is not harvested fresh, it is allowed to dry on the stalk and then is harvested with a combine. This type of corn is used primarily in animal feed or in cereal products.
"Corn" is in the NAICS Code "11115"
