The rain didn’t dampen the excitement of a new bioreactor being installed near Albert City last night. Olie and Lois Leimer were pleased to share their newest conservation practice on their farm with fellow farmers, landowners and contractors at our field day.
The Leimers are long time implementers of conservation practices. They began using no-till many years ago in an effort to save on fuel and time. They have also added cover crops to their farm to reduce soil erosion and improve soil health and water quality.
“It’s a work in progress. We’re always looking for ways to improve our farm and our impact on water quality,” state Olie.
Leimer approached the local Natural Resources Conservation Service about two years ago to begin the process of installing the bioreactor. Together with Lee Gravel, Headwaters of the North Raccoon Watershed Coordinator, and ISG in Storm Lake to design and construct the bioreactor, the finished edge of field practice will treat about 80 acres of drained row crop acres.
The actual installation process goes fairly quickly. The trench and control structures were installed on Monday and by Tuesday afternoon the woodchips were delivered. They would have finished on Tuesday, but the area was left open so attendees could view the trench and woodchips. In total there is about 3.5 feet of woodchips that will be covered by about one foot of soil. Once the soil is in place, a pollinator habitat mix will be seeded over the bioreactor.
The bioreactor will be monitored for how nitrate removal throughout the upcoming years as partners work to meet the goals of the Iowa Nutrient reduction strategy. If you are interested in installing a bioreactor on your farm you can contact Iowa Learning Farms or your local NRCS office.
