6b. Saturated Buffer

Saturated buffers contain underground “plumbing” to intercept water in the field tiles and redirect it into a buffer of grass, trees, and other plantings that can process nitrate and keep it out of adjacent streams.

  • Buffers remove sediment, phosphorus and pesticides and provides wildlife habitat above ground
  • Nitrate is removed through denitrification and plant uptake by the roots below the surface
