About 100 years ago, the Central Plains was called a prairie. A prairie is a piece of land that is flat and covered in tall grasses with wild flowers. In the prairies the grasses and flowers are naturally fertile.  The prairies usually get plowed to plant crops. Kansas and North Dakota are the country’s biggest wheat  producers.  Livestock or farm animals mostly graze in this area. Raising cattle, pigs,and chickens are important to the agriculture in the Middle West.  Farmers in Iowa can produce more than a billion bushels of corn in a year.                                                                                                                                                                                The plants that are grown are mostly fed to the farm animals.
