CP21 - Filter Strip - CRP/CREP
Wisconsin Job Sheet 393
Natural Resources Conservation Service (NRCS)
Landowner: ____________________________________ Tract: _________________
The CRP contract holder is responsible for
maintaining the entire filter strip area (see C below)
in appropriate cover. This includes areas without
cropping history between the top of the
streambank and the cropped field, areas already
functioning as a filter strip, wooded areas, pasture
areas, etc. The area of the filter strip under
contract must be maintained in the planned cover
according to Wisconsin Job Sheet 134 or 135.
The area of the filter strip not under contract must
be maintained in permanent cover. Grazing or
mowing with removal of material is not allowed in
Vegetation may need to be mowed on a regular
basis to allow the filter strip to function properly.
After establishment, mowing is not allowed from
May 15 through August 1 which is the primary
nesting season. Filter strips should be inspected
on a regular basis and repaired or reseeded as
needed. Sediment accumulations may need to be
removed. Regular vehicle traffic is not allowed.
Restoration of the filter strip will be required if so
much sediment has accumulated that the filter strip
is no longer effective.
Land within 300 feet of the filter strip must be
managed so that soil loss is at or below Tolerable
Soil Loss (T) Levels. Soil loss at levels above T
will soon overwhelm a filter strip with sediment.
Filter strips may not be installed unless soil loss is
at or below T.
