ErosionControl is the foundation for effective stormwater management
Sedimentation is a symptom. Chemical and nutrient runoff is a symptom. The problem is loss of soil organic matter.
McGill ErosionControl is formulated for control projects specifying blankets, berms and socks. It is a blended product and meets DOT-type specifications for management projects. For pneumatic applications, seed can also be blown with ErosionControl compost.
Two-thirds of sediment loss result from human activities like agriculture and development. The volume of water rolling off developed landscapes can be almost five times the amount shed by undisturbed soil. A drive past any construction site where silt fence is used will often provide ample proof that these types of erosion control devices don’t work.
Effective stormwater management and erosion control requires a two-phase approach:
- Compost socks, blankets and berms for short-term mitigation
- Compost-amended soil for long-term soil retention and runoff prevention
The McGill ErosionControl advantage
- Increase water retention — Reduce run-off. Prevent/reduce sheet and rill erosion.
- Create a protective buffer — Rainfall energy is absorbed. Fewer soil particles are dislodged. Soil compaction is reduced. Infiltration is increased.
- Remove pollutants from stormwater — Compost filters and degrades pollutants. Improves downstream water quality.
- Faster establishment of vegetation cover — Improves microbial activity, nutrient/water availability, and soil structure.
- Saves labor and landfill costs — Compost becomes a permanent part of the landscape. Nothing to remove when the project is complete. No plastic or fencing to landfill.
For short-term mitigation, use ErosionControl compost in socks and berms
ErosionControl offers a media with varying particle sizes to absorb rainfall energy. When energy is absorbed, fewer soil particles are dislodged.
Compost-based solutions also retain water, encouraging percolation and reducing runoff volumes. (READ: compost specifications for erosion control for highway projects from the U.S. Composting Council.)
Compared to traditional control methods, finished projects using compost-based mitigation strategies look better and blend better with the landscape. Compost blankets, berms and socks can be vegetated. Because they remain as a permanent feature of the landscape, no labor is required to remove temporary fences or other hardscape barriers. As a result, there are no landfill disposal fees, either.
For a long-term solution, amend the soil
Sedimentation and polluted runoff are symptoms of poor soil management. The cause? Loss of soil organic matter. For general erosion prevention and stormwater management, amend soil to rebuild and maintain topsoil.
At a recommended soil organic matter (SOM) content of 5 percent, soils demonstrate the ability to absorb as much as 100 percent of a typical 1-inch rain event. While compost socks, berms and blankets are excellent technologies for short-term management, soil amendment is a tool for managing stormwater runoff over the long-term.
Use a quality, all-purpose compost product like McGill SoilBuilder Compost. In clay soils, compost incorporation improves drainage by increasing porosity. In sandy soils, water-holding capacity and soil aggregation are increased.
The base ingredient of ErosionControl is McGill SoilBuilder compost, which is blended with wood chips and/or other ingredients to meet your project specifications.
