On Tuesday's AOA, powered by Cenex, we take a look at news headlines including comments on advocating in agriculture from American Farm Bureau President Zippy Duvall and some insights into the potential slowdown of Brazil soybean expansion due to cost pressures in Segment One. In Segment Two, we discuss a new Fungicide Timing Solution and have an agronomic conversation with Trent Brisby from Pioneer. In Segment Three, we have a conversation about EPA's announcements regarding diesel exhaust fluid (DEF) and the Renewable Fuels Standard and what it all means for agriculture. EPA Regional Administrator Cyrus Western joins us for a conversation. Then we close the show in Segment Four and learn more about From Dust: How the World's Smallest Resource Could Shape the Future, a documentary highlighting advances in drought-tolerant forage and improved cattle weight gain now seen across Texas, a region at the forefront of U.S. agricultural and food production. Sydney Anderson with Curtis and Curtis Seed Company joins us to discuss.
