Maize (Corn) is one of the largest crops grown in the united states, and a staple food in many first people/Native American dishes.
In the United States, a third of corn production is utilized to feed livestock like cattle, hogs, and chickens. Corn supplies the "carbs" and soybeans the protein in animal feed. According to some estimates, a beef cow grown on a feedlot can consume a ton of corn; two bushels of American maize are required to produce one serving of corn-fed steak. Cows that produce milk and beef both eat silage, which is made of fermented corn stalks and other green plants. A little over a third of corn production is utilized to produce ethanol, which is added to gasoline as a sustainable fuel. The Renewable Fuel Standard calls for 10% of gasoline to be renewable fuel, however, in some places, notably in the Midwest, you can get E15 (15 percent ethanol) or E85 (85 percent ethanol). The remaining corn harvest is either exported to other nations for use as food or feed, or it is used in the United States for industrial purposes, drinks, and human nourishment. There are many uses for corn. It is employed in the production of biodegradable packaging materials, tortilla chips, grits, canned beer, soda, and cooking oil. It is a crucial component of the growing medium used to produce life-saving medications like penicillin. To keep weeds from growing in flower beds, use corn gluten meal.
