Because of the weather, environmental issues, or public concern, an increasing amount of silt
fencing has appeared in contract descriptions. It is easy to find a project requiring a mile
or more of silt fencing installation, maintenance, and removal.
Sizing the compost material appropriately can greatly affect the amount of turbidity that is
removed from runoff. When compost is screened to a 3” minus, the varying sizes of material
offer different advantages. The larger material helps stabilize sloped
applications by absorbing some of the energy caused from moving water. The smaller fines
trap silt and other suspended material for assimilation
by bacteria. Compost is really a small factory, which by nature, is designed to manage water
efficiently while providing a healthy habitat.
