Will prairie strips plug tile lines?
Perforated tile are buried under cropland to remove excess water detrimental to crop production. Farmers and landowners considering installing strips of prairie plants in their fields have asked about the possibility of roots growing into tile lines. To address this potential, Tim Younquist and Matt Helmers used video cameras to evaluate root penetration into the tile lines under prairie and continuous corn.

How are prairie strips different from contour buffers and grass strips?
Contour buffers are typically planted with fixed widths. In contrast, we vary the width of the prairie strips based on the amount of water they intercept, with the goal of treating all of the runoff leaving the crop field. Where more water is flowing down-slope, prairie strips should be wider, and where less water is flowing down-slope, the strips can be narrower.
Are prairie strips only for organic operations?
Prairie strips are a conservation tool that can be used in both conventional and organic farming operations. In conventional farming operations, precision herbicide management is useful. Native forbs (i.e., wildflowers) in the prairie strips are broadleaf plants and can be damaged or even killed by direct contact with herbicide. Once established, native grasses and forbs have deep root systems that help create a durable, resilient plant community.
