Focus on the Future - INRC Spring 2024 Seminar Series - March

Wednesday, March 6, 2024 - 3:10pm

The Iowa Nutrient Research Center's Spring 2024 Seminar Series will Focus on the Future – Students & Their Contributions to Water Quality Research. Hybrid monthly sessions from 3:10-4:00 p.m. take place online and at 1306 Elings Hall on the Iowa State University campus.

Sessions feature current and former graduate students who are or have been involved with water quality research at Iowa State.

Reducing phosphorus export in farmed potholes using blind inlets with steel media.
Presenter: Adam Buseman, Water Quality Project Manager, King County, Washington.

The Prairie Pothole Region has numerous farmed potholes that can become inundated with phosphorus (P) enriched surface waters after large rain events. This research quantifies soil P concentrations within farmed potholes and investigates replacing a Hickenbottom surface intake with a blind inlet containing steel media to reduce P export.

Water quality impacts of perennial ground cover in tile-drained corn production.
Presenter: Gabrielle Myers, Department of Agricultural and Biosystems Engineering. Advisors: Raj D Raman and Daniel Andersen.

The perennial groundcover (PGC) approach proposes the use of continuous soil cover through perennial plant species growing in conjunction with the annual row crop. I will be presenting the results of a three-year field study comparing the yield and subsurface drainage water quality impacts of conventional corn production, annual cover crops and a Kentucky bluegrass PGC. The study took place at the long-established water quality research sites at Iowa State's Northeast Research and Demonstration Farm amidst three growing seasons of unusual precipitation.
