Definition:
A strip or area of vegetation for removing sediment, organic
matter, and other pollutants.
Purpose:
To remove sediment and other pollutants from runoff by processes
such as filtration, deposition, infiltration, absorption,
and volatilization, thereby reducing pollution and protecting
the environment.
Criteria:
Apply this practice on cropland at lower edge of field,
in areas requiring filter strips as part of a system to treat
polluted runoff. Appropriate filter strip size is related
to the type of pollutants being filtered, the filter strip
slope and the drainage area being treated.
*This is not intended as a how to guide.
Individual practices must meet minimum standards and comply
with local laws and regulations. For more information contact your
local RCD or NRCS office. |
