 From the Iowa Agribusiness Radio Network studios in Des Moines, I'm Mark Magnuson, and welcome to Iowa Ag Matters. In today's show, Riley speaks with Brandon Hume, champion agronomist to learn about in-season nitrogen application. Andrew Penny of DeKalb will join Andy to talk about tar spot, and I visit with Eric Wilson of Wiffles as we continue the discussion about agronomic issues in Iowa. It's time now to welcome our hosts, Dustin Huffman and Andy Peterson.
