AMES, Iowa — Iowa Learning Farms, in partnership with Poweshiek County Soil and Water Conservation District, Iowa Soybean Association, Poweshiek County Farm Bureau and Iowa Corn, will host a bioreactor field day Thursday, Aug. 23,  5:30-7:30 p.m. at Roger and Louise Van Ersvelde’s farm, rural Brooklyn. The event is free, open to the entire family and includes a complimentary meal.

bioreactor installation.Edge of field practices like wetlands, saturated buffers and bioreactors are key to reducing nitrate loss from agricultural land in Iowa. Through a natural biological process microorganisms living in the systems use the incoming nitrate for respiration and reduce the nitrate levels from incoming tile drainage. Together with in-field practices like cover crops and no-tillage, these practices will help reach the Iowa Nutrient Reduction Strategy goals.

Field day attendees will have the opportunity to view and learn about the bioreactor installed on the Van Ersvelde farm as part of their conservation and land stewardship goals. A demonstration by the Iowa Learning Farms On The Edge trailer will discuss what is happening beneath the surface in bioreactors and saturated buffers. Keegan Kult, Iowa Soybean Association, will discuss the site selection process and technical design of bioreactors. Landowner Roger Van Ersvelde will share information about the design, installation and performance of  his bioreactor. Mindy Sieck, Little Bear Creek Watershed Improvement Project coordinator, will provide an update on the project and share opportunities to get involved.
