Plan variable-width buffer with BufferBuilder
Traditionally, farmers have been asked to install constant-width filter strips. These buffers are designed to handle water moving through the filter strip in a uniform flow, with no consideration of rotations or tillage systems.
Overland runoff is not uniformly distributed; it tends to concentrate within channels before reaching the stream. Therefore, a constant-width filter strip can become overwhelmed and would be only marginally effective. Additionally, where low water flows exist, the standard 50 foot buffer may be overkill because there is very little water movement and sediment to trap.
Additionally, very little consideration has been given to the width of filter strip required based on the upland treatment. Changes in tillage systems can have a big impact on sediment delivery.
Now by correctly designing variable width filters, and modifying tillage systems, a farmer can achieve the same water quality benefits of a constant width buffer while taking significantly less land out of production.
Agren® BufferBuilder allows conservation planners to custom-design buffers to trap sediment as water flows off a field. Using site-specific management systems, soils, and topographic information, BufferBuilder models the flow of water and sediment from a crop field. This technology identifies where filter strips will be the most effective and helps the user properly design the width along the water body.
With BufferBuilder, you can:
- Easily distinguish areas of high sediment delivery
- Target buffers to high sheet and rill erosion areas
- Protect water quality while minimize land removed from production
- Create a custom PDF plan of the buffer location.
- Download a GIS layer that can be loaded into other GIS software programs
- All calculations are based on RUSLE2
BufferBuilder is the latest offering in the Agren tool suite to help farmers install precision conservation practices, customized to each operation’s unique landscape and needs. Different licensing options are available. Contact us to determine a solution that works best for you.
All calculations are based on LiDAR and use established design standards.
