Using compost to improve stormwater management and erosion control on roadsides
September 2007 Roundtable & Living Field Demonstration - Retzer Nature Center, Waukesha, WI
Benefits of Compost In Stormwater Management & Erosion Control
- Prevents or reduces erosion
- Retains water & reduces run-off rates
- Assists in establishing vegetation with vigorous root growth
- Improves soil structure & porosity, buffers pH & provides beneficial microorganisms
- Retains sediment, while allowing clear water to pass through
- Retains pollutants such as heavy metals, oil, fuel, pesticides, etc.
- Bioremediates trapped nitrogen, phosphorus nutrients, oil fuel & some pesticides
