Webinar: Impacts of Wetland Restoration and Drainage Improvements

May 2, 2022

The Iowa Learning Farms (ILF) conservation webinar taking place May 11 at noon CDT will feature William Crumpton, university professor at Iowa State University. Dr. Crumpton’s research focuses on wetland processes and functions, including the dynamics of energy flow and nutrient transformation in wetlands, the fate and effects of agricultural contaminants in wetlands, and the role of restored and constructed wetlands in watershed hydrology, greenhouse gas emissions and water quality.

Iowa Learning Farms is an Iowa State University Extension and Outreach conservation and water quality education program.

In the webinar, “Integrating Drainage Improvements and Wetland Restoration in Iowa: Environmental Impacts of Improved Drainage and Targeted Wetland Restoration,” Crumpton will discuss results of a multi-year study examining the effects of improved drainage on nutrient export from agricultural catchments and the effectiveness of wetlands in reducing downstream nutrient loads from these systems. He will also discuss the opportunities for integrating targeted wetland restorations within existing and future agricultural drainage systems with an eye toward reducing or mitigating the export of nitrogen and phosphorus to waterways.


“Agricultural drainage systems are the primary pathway by which nonpoint source nitrogen and phosphorous loads are delivered to Iowa surface waters, and targeted wetland restoration is one of the most promising strategies to intercept and reduce these nutrient loads,” said Crumpton. “As agricultural drainage systems are replaced and upgraded, it is critical that we understand the impacts of drainage modifications on nutrient export and the potential for mitigating those impacts using wetlands and other edge of field practices.”


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.
