Corn is grown in most states, but the largest portion of it is grown the heartland of the United States. Farmers grow more than 90 million acres of corn each year, making the United States the world's largest corn producer.
Corn is a wind pollinated plant so while bees and other pollinating bugs may buzz around the tips they don’t carry pollen from one plant to the others. The silky strands at the top of corn are there for pollination and each single silk is attached to each potential kernel in a cob. This means that a severe rainstorm could lead to lots of “empty” kernels.
Sweet Corn is what people eat straight off the cob, while Field Corn is a very important crop used for animal feed. Field Corn is also used to make food products like cornmeal, corn chips and corn syrup.
