From VOA Learning English, this is the Agriculture Report.Farmers in the United States are concerned about a possible decrease in the use of ethanol. Ethanol is a liquid fuel made from plants, such as corn.Last November, the Environmental Protection Agency proposed lowering the required amount of ethanol mixture in the nation's gasoline supply.The required use of ethanol in fuel began in 2007. The requirement was part of a law called the Energy Independence and Security Act.The law established a Renewable Fuel Standard, or RFS. The RFS ordered fuel refineries to mix ethanol into their gasoline to cut the use of non-renewable fuels.The required amount was to increase over time. That requirement was good news for corn growers like Brian Duncan of Polo, Illinois.He thinks the proposed changes will hurt corn sales. He says that after a poor harvest in 2012, farmers enjoyed some of their best corn harvests in 2013."As we look at the increased bushels, our inventories are gonna be worth $3 a bushel less than what they were valued at a year ago," said Duncan.
