FIELD BUFFERS

• Vegetated filter/buffer strips

The vegetative filter strip along the outlet end of the field and parallel to the outlet ditch is used to remove sediment, pesticides and nutrients from the runoff prior to entering the ditch.  Vegetative filter strips produce clean clear water leaving a field.  To qualify as a vegetative filter strip it must be a minimum of 30’ wide. 

•  Field Borders

The field borders protect adjacent wooded wetlands.  The strips are planted to mixtures of Alamo switchgrass, big bluestem, and indiangrass to trap sediments and nutrients before entering the wooded wetland.

• Grassed Waterways

The grass waterways are planted to bermudagrass interspersed with Alamo switchgrass plantings to slow water flow and allow soil sediments to settle out, and filter nutrients before water leaves the farm. 

• Grass Turn Roads

The grass waterways are planted to bermudagrass interspersed with Alamo switchgrass plantings to slow water flow and allow soil sediments to settle out, and filter nutrients before water leaves the farm. 

• Constructed Wetland Ditch

This practice is used to filter soil sediment, pesticides and nutrients from the field runoff.  Vegetation includes: maidencane, cattails, johnsongrass, willow trees, switchgrass.  Vegetation also provides habitats and protective cover for wildlife.
