Prairie Strips

What Are Prairie Strips? Small portions of crop land are taken out of production and planted with native prairie plants for conservation benefits for the entire field. Prairie strips at Neal Smith National Wildlife Refuge outside of Prairie City, Iowa. NRCS/SWCS photo by Lynn Betts.

Why use Prairie Strips? Photo credit: Jose Guttierez Lopes By planting 10% of a field into 15 ft to 30 ft strips of prairie along the contour, farmers can reduce soil movement by 95%.

Why Use Prairie Strips? Prairie strips increase the diversity of plant species, which in turn attracts pollinators and creates habitat for wildlife.

What Can Prairie Strips Do for Water Quality? Prairie strips can also have a major effect on nutrient loss from farm fields: • Reducing phosphorus loss by up to 90% • Reducing nitrogen loss from surface water by up to 85% Prairie strips on Tim Smith’s land in Wright County, Iowa.

Benefits of Prairie Strips • • 44% reduction in water runoff 95% reduction in soil loss 90% reduction in phosphorus runoff 84% reduction in nitratenitrogen runoff No difference in per acre corn and soybean yields No difference in weed abundance Reduced emissions of heattrapping gases, especially nitrous oxide Potentially improved beneficial insects and wildlife Gray-Headed Coneflower Butterfly Milkweed NRCS/SWCS photos by Lynn Betts.

What Is the Cost of Prairie Strips? Estimated to cost between $24 and $35 per treated acre per year. Cost share is available through: • NRCS: Code 393 (filter strip), Code 332 (contour buffer strip), CRP Practice CR 33 (habitat buffer) • FSA (Pollinator Enhancement Program) • US Fish and Wildlife Partners Program • IDALS • Pheasants Forever • Trees Forever Prairie Strips Prairie strips in their first year in Tama County, Iowa.

How to Establish Prairie Strips? Prairie strips take about three years to establish. Prairie strips should be planted in the fall (after harvest) or in the spring (before June 30 in Iowa).

How to Establish Prairie Strips? A good phrase to remember about prairie is that “the first year it sleeps, the second year it creeps, and the third year it leaps. ” Year 2 Year 3 Year 1 NRCS/SWCS photos by Lynn Betts.

How to Establish Prairie Strips? Year 1: Prairie Strips will look “stubby” and need consistent mowing in order to develop a diverse plant mix. Year 2: Some forbs (flowering plants) will start to bloom. Some mowing and spot application of herbicide may be needed. Year 3: Should begin to resemble a tallgrass prairie. Some spot application of herbicide may be needed. The strips can also be managed with baling or prescribed burns. NRCS/SWCS photos by Lynn Betts.
