A field border is a type of conservation buffer consisting of a grassy border along one or more edges of a field. In Minnesota, field borders are usually at least one rod (16.5 feet) wide.
In addition to the soil and water protection provided by the perennial vegetation, field borders can be designed to provide other environmental and practical benefits. For example, field borders can straighten irregular field boundaries and provide space to turn and park tractors during field operations. Field borders can also harbor natural predators of crop pests and provide wildlife habitat.
