Webinar: Water Quality Benefits of Two-Stage Ditch Construction | Building a Culture of Conservation

Webinar: Water Quality Benefits of Two-Stage Ditch Construction

March 14, 2022

The Iowa Learning Farms (ILF) conservation webinar taking place March 23 at noon CDT will feature Jennifer L. Tank, Galla Professor, Department of Biological Sciences, University of Notre Dame. Tank is an aquatic ecologist and biogeochemist who studies how nutrients move through streams and rivers. Her research focuses on innovative conservation and restoration practices that support and inform effective management of freshwaters, especially in agricultural landscapes. Her recent work utilizing two-stage ditches in restoring floodplains feeding into formerly incised streams will be the focus of this webinar.

In the webinar, “The Two-Stage Ditch: Improving Water Quality in Agricultural Waterways via Floodplain Construction,” Tank will highlight the benefits in nutrient transport reductions realized through a demonstration project in Indiana where a two-stage ditch was implemented. She will share findings that show improvements in water quality that include increased biological nitrate-N removal, dissolved phosphorus retention and reduced suspended sediments, especially during high flows.

“The movement of nutrients from farm fields into waterways is often exacerbated by storms and heavy rainfall, resulting in a higher potential for degradation of local and downstream water quality,” said Tank. “Given predictions that storm frequency and intensity will increase in the future, we need to maintain productive agriculture and effective drainage, while also preventing nutrient and sediment losses to sensitive downstream ecosystems. The two-stage ditch is one innovative practice in the nutrient management toolbox that has demonstrated water quality benefits. We are hopeful that this and other conservation practices can continue to contribute to the innovative management of our agricultural waterways.”

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.
