The Iowa Learning Farms (ILF) conservation webinar taking place April 20 at noon CDT will feature Dr. Keith Schilling, state geologist and director, Iowa Geological Survey. Schilling conducts research on water-related issues in Iowa that include groundwater flow and quality, surface and groundwater interaction, nonpoint source pollution and watershed and flood plain processes. One goal of this research is to better quantify the contribution of phosphorus (P) loads in Iowa’s waterways from streambank erosion.
Iowa Learning Farms is an integral program of Iowa State University Extension and Outreach.
In the webinar, “Contribution of Streambanks to Phosphorus Export in Iowa,” Schilling will discuss a collaborative study in which a variety of methods and a multistep process were employed to help determine the amounts of P originating from streambank erosion in relation to total P levels in waterways. He will also elaborate on the challenges associated with evaluating streambank erosion and the long-term average contribution of streambanks to total P export from Iowa.
“Streambank erosion is thought to be a potentially large contributor to sediment P loads in agricultural watersheds, yet reduction and mitigation of streambank losses is seldom accounted for in nutrient reduction strategies and practices,” said Schilling. “We anticipate that the results of this study will help increase awareness of streambank P contributions and will help inform decisions about implementing effective soil and water conservation practices that best reduce P loading in streams and rivers.”
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.
