AMES, Iowa—Iowa Learning Farms, in partnership with the Iowa Nutrient Research Center, Conservation Learning Group, and Prairie Rivers of Iowa, is hosting a free virtual saturated buffer field day on Thursday, June 11 at 1pm CDT. Join us as we explore the first-ever saturated buffer that was installed in 2010 within an existing riparian buffer along Bear Creek in Hamilton County.
The event will include video footage from the field and live interaction with Tom Isenhart, Iowa State University Professor, Billy Beck, Iowa State University Assistant Professor and Extension Forestry Specialist, and Dan Haug and David Stein of Prairie Rivers of Iowa. Together they will discuss how saturated buffers, riparian buffers and pollinator habitat work together to improve water quality, farm aesthetics, and wildlife opportunities.
Riparian buffers are a proven practice for removing nitrate from overland flow and shallow groundwater. However, in landscapes with artificial subsurface (tile) drainage, most of the subsurface flow leaving fields is passed through the buffers in drainage pipes, leaving little opportunity for nitrate removal. Isenhart, along with Dan Jaynes, Research Soil Scientist with the National Laboratory for Agriculture and the Environment (USDA-ARS), pioneered the process of re-routing a fraction of field tile drainage as subsurface flow through a riparian buffer for increasing nitrate removal - creating the first-ever saturated buffer that will be featured during this virtual field day.
“The Bear Creek saturated buffers are prime examples that trees and perennial vegetation can work in agricultural watersheds – benefitting both water quality and the Iowa producer,” notes Beck whose research and extension programming focuses on the impacts that trees, woodlands, and forests have on water quality and quantity in the Midwest.
