Iowa Learning Farms Webinar: Making Water Quality Impacts at the Edge of Fields

January 12, 2022 @ 12:00 pm

The Iowa Learning Farms (ILF) conservation webinar taking place Jan. 12 at noon CST will feature Matt Helmers, professor in the Department of Agricultural and Biosystems Engineering at ISU and director of the Iowa Nutrient Research Center. Helmers leads research on the impact of agricultural management and conservation practices on water quality. He will draw on his expertise with field drainage systems and drainage water quality in this session.

In the webinar, “Better Utilizing the Field Edge: Saturated Buffers and Bioreactors,” Helmers will overview a broad range of edge of field practices that can help remove nitrates from drainage water and prevent or reduce loss to waterways. He will also take a closer look at how saturated buffers and bioreactors can address the increasing nitrate levels being found in drainage water from tile systems. The session will also highlight educational tools that can be used to improve understanding of these practices and factors to consider in selecting and siting practices for success.

“Edge of field practices such as bioreactors, saturated buffers, wetlands and oxbows have potential to remove nitrate before it can be delivered to the stream, but must be utilized in the correct sites and circumstances,” said Helmers. “The good news is that there are so many different edge of field practice options, there should be at least one good match for every farm, field or situation. All of these practices play a role in reducing downstream nitrate delivery and are critical for local and regional water quality improvement.”

Participants in Iowa Learning Farms Conservation Webinars are encouraged to ask questions of the presenters. People from all backgrounds and areas of interest are encouraged to join.
