    Farm Economy Pressures Mount as Corn Growers Look to Ethanol and Diversification

    In this episode of the Iowa Ag Podcast, host David Geiger sits down with Mark Mueller, president of the Iowa Corn Growers Association, to talk about the economic and policy pressures facing corn farmers today. From ethanol policy and year-round E15 access to international trade opportunities, Mueller explains how expanding markets for corn could help support farm profitability during a period of tight margins. 💡 Find this show on your favorite player: https://iowapodcast.com/farm-economy-pressures-mount 🗞️ Be first to get new interviews: https://iowapodcast.com/subscribe/ 🐖 Get a free $30 gift card from Jethro's BBQ: https://iowapodcast.com/jethrosbbq The conversation also explores a topic Mueller believes is just as important as policy: communication. Farmers today wear many hats, from agronomists and mechanics to ambassadors for agriculture. Mueller shares why it's increasingly important for farmers to engage with consumers, lawmakers, and their communities to explain how modern agriculture works and why trust between farmers and the public matters more than ever.
