How Prairie Strips Address Midwestern Farmer Challenges

Challenge #1 How can Prairie Strips reduce Soil Erosion?

The flumes pictured below are used to measure runoff from the STRIPS watersheds. Note the difference in the amount of sediment displaced between pictures 1, 2 and 3. Picture 1 represents a 100% no-till crop field with corn and soybean rotation compared to just 10% prairie treatment in picture 2 and 100% prairie in picture 3.

Prairie Strip Installation and Establishment

Installation and Establishment

Prairie strips are most easily established in fields which have previously been used for tilled annual row crop production (Jarchow and Liebman, 2011). Seeding following soybeans is especially favored for prairie strip establishment because the tilled field will have a reduced seed bank of annual weed seed and the soybean stubble will decompose readily (Jarchow and Liebman, 2011).

Nonetheless, if the correct procedures are followed prairie can be easily established following any crop or land cover. Read more about Prairie Strip Installation and Establishment

Research Overview

Helmers-Watkins-Liebman NSNWRThe STRIPS project began in 2003, when Iowa State University scientists began discussing the opportunity to test the effects of integrating restored prairie in crop fields with managers at Neal Smith National Wildlife Refuge. Together, the scientists and refuge managers established four different treatments on 12 small watersheds at Neal Smith in 2007. As of 2012, we're now also working on a growing number of commercial farm fields across Iowa and northern Missouri.

Frequently Asked Questions

Prairie strips at NSNWR by Meghann JarchowPrairie strips is a farmland conservation practice that uses strategically placed native prairie plantings in crop fields. The practice has been tested by the STRIPS team since 2007 on experimental plots at the Neal Smith National Wildlife Refuge and increasingly on commercial farms across Iowa. Here we present our responses to the Frequently Asked Questions we receive on prairie strips at conferences and field days, and through email. The information was prepared by team members, and will be updated over time as needed, as we continue to learn. The answers below are general in nature, and may not apply in specific situations. Resources are provided with each answer. Read more about Frequently Asked Questions
