The final practice included in the Whole Farm Conservation Best Practices manual is prairie strips. These areas of perennial vegetation address three main resource concerns (soil erosion, nutrient loss, and wildlife habitat)
Prairie species have stiff stems and deep roots that slow down water, allow it to infiltrate, and filter out sediment and nutrients. Patches of native perennial vegetation create valuable habitat for a wide variety of birds, insects, and mammals.
Prairie strips can be placed around the edge of a field, within the field, alongside or perpendicular to waterways, and in terrace channels. To provide erosion control, improved water quality, and wildlife habitat, a minimum of 10% of the field should be converted to prairie. Prairie strips should have a minimum width of 30’ and be spaced at intervals that work with your farming equipment.
Check out the decision tree below to see if prairie strips can work for you!
Prairie flowers and grasses take time to establish, typically requiring two to three seasons of establishment management. Annual and perennial weeds grow quickly and can outcompete prairie plants in the first two growing seasons. Mowing prairie is an essential management practice that must be done during the first year whenever the height of the vegetation reaches twelve inches. Mower height should be set to four to six inches.
