Description: Presenters will discuss major findings from three recent saturated buffer field research studies in Iowa, offer insights into improving design approaches based on new data, and share landowner perspectives on research and management.

Authors: Lee Tesdell (Tesdell Century Farm)*

Author Bio: Gabe Johnson recently finished his PhD in Sustainable Agriculture and Agricultural and Biosystems Engineering at Iowa State University. His research, advised by Drs. Tom Isenhart and Michelle Soupir, focused on design and effectiveness of edge-of-field practices (saturated buffers and denitrifying bioreactors) for removing nitrate from agricultural drainage water. He was responsible for monitoring and data analysis of the saturated buffers on the Tesdell Century Farm.

Lee S. Tesdell is the owner of Tesdell Century Farm in Polk County, Iowa. He is retired from Minnesota State University, Mankato, where he taught courses in the technical communication program. He has installed in-field and edge-of-field practices on his farm and was recently elected to the Polk County Soil and Water Conservation District as a commissioner.
