Corn and Ethanol: Green, Getting Greener Rick Tolman National Corn Growers Association
2007 a Very Good Year Production reaches 13.1 billion bushels Largest crop in U.S. history Average yield hits 151.1 bushels/acre The second-highest yield estimate in history
2007 Corn Supply and Demand Other Domestic Ethanol Surplus Export Feed Total Supply: 14.4 billion bushels Feed: 42% Ethanol: 22% Export: 17% Other Domestic: 9% Surplus:10% USDA 1/2008
Outline A. Meeting Demand B. Reducing Inputs C. Rational Approach to Sustainability
A. Three Steps to Meeting Demand 1. Increase corn production by boosting average corn yield significantly 2. Displace more corn in feed use with coproducts 3. Improve efficiency to squeeze more ethanol from each bushel of corn

Corn s Water Needs Approximately 20-25 inches of water are necessary to produce an acre of average-yielding corn This translates to about 597,388 gallons per acre per year, or nearly 4,000 gallons per bushel Based on 22 acre-inches (U of KY)
What They Don t Tell You Nearly nine out of ten acres of corn require no water other than natural 13% Irrigated 13% 87% Non-Irrigated rainfall Source: USDA 2006
What They Don t Tell You An acre of corn gives off 4,000 gallons of water a day in evapotranspiration About 1 to 1.5 million gallons of moisture per acre annually
Corn: Water Positive In aggregate, corn returns more moisture to the atmosphere than it withdraws from ground and surface water for irrigation 12.4 million acres require 9.22 billion gallons of surface and ground water irrigation per day But the entire corn crop (~83 million acres) is returning about 290 billion gallons of water per day to the atmosphere through transpiration* * 3,500 gallons per day per acre
Water Use in Production 62,600 gallons to produce a ton of steel 39,090 gallons are needed to manufacture a new car, including tires 28,100 gallons to process a ton of beet sugar to make processed sugar 1,500 gallons to process a barrel of beer Source: USGS/USEPA

Land Use Controversy Finally, these analyses published in Science may not be termed life cycle analyses. Life cycle analysis (LCA) follows a specific set of rules, one of which is that the most recent and most appropriate data be used. LCA is data driven, but these two analyses are not driven by actual data at all. There are no real, verifiable data in either of these papers on the land use changes that actually occur as more corn is processed to ethanol hence these are not LCA studies. They are in fact speculation. Even if there were such data, ethanol produced in the United States under a specific set of production criteria would not be responsible for anything but its own environmental profile. Dr. Bruce Dale, MSU
Land Use Controversy Brazil can produce twice as much grain and ethanol as it now produces today without clearing another hectare of land. Deforestation is driven by the hypocrisy of those that shout about saving the Amazon Forest, but are willing to pay a fortune for Amazon hardwood for their buildings, home and furniture. If trade in hardwood is prohibited, deforestation will stop. Alfredo Navarro

Our working definition of sustainable agriculture Sustainable agriculture will meet the needs of the present while improving the ability of future generations to meet their own needs by: Increasing productivity to meet future nutritional and fiber needs while decreasing impacts on the environment Improving human health through access to safe, nutritious food Improving the social and economic well being of agricultural communities The initial work will focus on the first aspect of sustainable agriculture (first bullet above).
Proposed outcomes Better informed decision-making throughout the agricultural supply chain from grower to consumer A sustainability tool for growers to map and improve their own performance An index based on measurable outcomes that can assist in setting performance goals Documented improved performance over time A single platform that entities throughout the supply chain can use in their sustainability efforts
