FAQ: Can I graze cattle on my prairie strips?

Can I graze cattle on my prairie strips?


This is an open question for the STRIPS team, which we hope to answer soon. At least two of our farmer cooperators are planning to graze their prairie strips: one is developing a method to rotationally graze the prairie strips and another releases cattle onto his whole field after fall corn harvest. Stay tuned for research results; in the meantime, you might try it, being careful not to allow livestock to congregate in any area long enough to create bare ground.

FAQ: Will prairie strips plug tile lines?

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.  Read more about FAQ: Will prairie strips plug tile lines?

FAQ: Why did you start your experiment at a National Wildlife Refuge?

Page

Iowa’s plentiful agriculture draws on the diminishing heritage of native prairies: rich soils, biodiversity, cleaned water and controlled erosion –  services that are impaired by today’s agricultural practices. Are there practices that mix row-crop agriculture and prairie to develop win/win systems? The 6,400-acre Neal Smith National Wildlife Refuge in Jasper County in central Iowa provided a unique opportunity for researchers to test practices on a "whole" watershed.

FAQ: Will prairie strips help pollinators?

Page

Prairie strips provide both abundant and diverse flowering plants to agricultural landscapes, which are essential for supporting honey bees and conserving wild bees and butterflies. Flowers provide critical food resources for these insects: nectar for adult bees and butterflies, and pollen for the young bees. Furthermore, a growing body of scientific literature indicates that bee health is improved when they are provided a diverse diet of plants. Read more about FAQ: Will prairie strips help pollinators?

FAQ: Will prairie strips eliminate erosion completely?

Page

Prairie strips will not completely eliminate erosion, and you may still need grass waterways. Data from our initial work at Neal Smith National Wildlife Refuge has shown that prairie strips can dramatically reduce sediment loss from the field, but there are still signs of in-field erosion, especially along the fall line of the watershed where a grass waterway could be quite effective.

FAQ: How are prairie strips different from contour buffers and grass strips?

Page

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.

FAQ: Are prairie strips only for organic operations?

Page

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. Read more about FAQ: Are prairie strips only for organic operations?
