How it works
Strips of permanent vegetation are established on the outside edges of a field. Permanent vegetation replaces crop end rows that would be planted uphill and downhill and be highly erosive. Field borders are often used with contour farming, terraces and contour strip-cropping systems.
Purpose/Benefit
- Reduces sheet and rill erosion by slowing the flow of water
- Filters runoff to improve water quality
- May be harvested in some cases and are easier to turn equipment on than some end rows
- Provides cover for small birds and animals
