Benefits of Buffer Strips Around Your Fields

Buffer strips are a simple concept, but have many benefits to farmers and commercial growers looking to improve soil health, reduce erosion, and promote sustainable land management. These strips of vegetation are planted along field edges, waterways, or drainage areas. They typically consist of native grasses, wildflowers, or cover crops. While they offer direct agronomic benefits, buffer strips also serve as valuable habitats for wildlife and can provide added opportunities for hunters.

Let’s explore what buffer strips are, how they benefit farmers, and why they’re gaining popularity in agriculture operations.

What is a Buffer Strip?

A buffer strip, or sometimes referred to as either a conservation buffer or vegetative buffer, is a designated zone of perennial vegetation strategically planted between cropland and sensitive areas such as waterways, ditches, or wetlands. These strips act as living barriers that filter runoff, stabilize soil, and enhance biodiversity.

Types of Buffer Strips

There are various types of buffer strips, and the selection of your vegetative strip should be strategic based on your land type. 

Grass filter strips: Narrow bands of grass that slow and filter surface water runoff.

Riparian buffer strips: Vegetated areas along streams or rivers to protect water quality and aquatic habitats.

Contour buffer strips: Alternating bands of grass or shrubs planted along field contours to reduce slope erosion.

Field Borders: Located at the edge of fields, providing a transition area between cultivated land and other areas. They can help reduce wind and water erosion, provide wildlife habitat, and offer space for equipment turning

The design and composition of buffer strips depend on land use, slope, and soil type, but their goal remains the same: to protect the long-term productivity of the farm while supporting the surrounding ecosystem.

Benefits of Buffer Strips to Farmers

While buffer strips do take away a few acres of operable farmland, they have many more benefits that make up for the loss of farmland. The long-term benefits here will help your farming operation stay profitable long after the first season of installing your buffer strip. 

Erosion Control and Soil Protection

One of the most immediate benefits of buffer strips is their ability to reduce soil erosion. By slowing water flow and encouraging infiltration, buffer strips keep valuable topsoil where it belongs…on your field. This is especially important for sloped land or areas prone to runoff during heavy rains.

Improved Water Quality

Buffer strips act as natural filters, capturing sediments, pesticides, and excess nutrients before they reach waterways. This not only protects local streams and rivers but also reduces the risk of contamination that could affect crop health or lead to regulatory issues.

Enhanced Soil Health and Microbial Activity

Buffer zones with diverse plant species encourage beneficial microbial activity in the soil. These microbes play a key role in breaking down organic matter, fixing nitrogen, and promoting nutrient cycling. As regenerative farmers, this is a major benefit to us to maintain healthier, living soil. 

Increased Pollinator and Beneficial Insect Habitat

Planting native wildflowers or flowering cover crops in buffer strips can attract pollinators like bees and butterflies. These strips can also support beneficial insects that help control crop pests, reducing the need for chemical pesticides.

Added Benefit for Hunters

Buffer strips provide critical habitat for game birds such as pheasants, quail, and turkeys, as well as deer, rabbits, and other small mammals. These areas offer shelter, nesting sites, and a reliable food source in otherwise heavily cultivated landscapes.

If you have a food plot, this buffer strip can act as a plot screen, and provide a sense of safety and security for the wildlife on your property. 

For plot screens, we recommend a seed mixture of sorghums and native grasses to plant around your food plot. A perennial blend of clovers such as Ridgeline Seed’s Triple Diamond Clover is a great seed blend for perimeter buffers along shaded treelines and waterways.
