We're at the Iowa Corn Wetlands Field Day presentation at Mark Mueller's farm in Waverly, Iowa to see first-hand the new clean water wetland system on his operation. First, we have a conversation with U.S. Senator Charles Grassley about a variety of issues on his radar in Washington. And we speak with Shane Wolfe, Wetlands Project Manager at the Iowa Department of Agriculture and Land Stewardship, and Iowa Dept. of Ag environmental engineer Mike Bourland about the project. And Mark Mueller joins us to take us through the reasons and process of having the wetland system.
