Wednesday, April 27, 2022 – 3:10pm

Presenter: Chad Penn is a soil chemist with the USDA-Agricultural Research Service and Purdue University.

Dissolved phosphorus (P) loss from high P soils is a long-term problem that conventional BMPs are unable to address. Phosphorus removal structures are landscape-scale filters designed to remove dissolved P from flowing water at “hot spots” until soil P levels have been reduced. This presentation will describe how P removal structures work, provide an overview of several styles of structures with performance and economics, and introduce the nature of the design process and design software, P-Trap.

The seminar series will be presented online and in-person at 3306 Elings Hall, 605 Bissell Road, on the Iowa State University campus. Sessions are free and open to the public, but participants are asked to register in advance at: https://go.iastate.edu/VEMYRK.
Presentations will be recorded and posted on INRC’s website with speakers’ permission.
