The
relationship between water quality and soil erosion cannot be overemphasized.
Soil erosion and residue management, especially surface water runoff, influence
water quality. A silt fence, sometimes called a filter fence, is a temporary
sediment control barrier used on construction sites to protect water quality in
nearby waterways from sediment in stormwater runoff.
The
problem with silt fences is that they only filter sand and silt, clay and nutrients
flow through the fences. Placing a berm
of compost on the low side of silt fences adds the capacity to filter out clays
and nutrients. Compost contains both positive and negative charges that attract
both positively and negatively charged elements and clays.
