Iowa Learning Farms has hosted a number of field days in 2016 where people have come together to learn about conservation farming practices. At these events, many attendees have had common questions, and sometimes common misconceptions, about water quality and drainage. Dr. Matt Helmers will explore some of these misconceptions and will touch on drainage practices that you might hear about more in the future such as drainage water recycling.
One common question asked at field days is what might need to change to reach our nutrient reduction goals. Helmers commented, “Many are surprised by the magnitude of change. Under some scenarios, we need on the order of 7,600 wetlands and 120,000 bioreactors on the land, in addition to cover crops on over 10 million acres.”
Helmers is the Dean’s Professor in the College of Agriculture and Life Sciences and Professor in the Department of Agricultural and Biosystems Engineering at Iowa State University, where he has been on the faculty since 2003. His research focuses on the impact of nutrient management, cropping practices, drainage design and management and strategic placement of buffer systems on nutrient export from agricultural landscapes.
