Compost Helps Manage Water Runoff
The Iowa Department of Transportation provided funds for Dr. Thomas Glanville, professor at Iowa State University, to conduct a study to determine how compost blankets would control erosion and sediment runoff at highway embankment sites.
The study compared subsoil compaction, a 6” topsoil cover and a 2-4” compost blanket.
What they found in the study was that the highway embankments blanketed with compost stopped erosion to a significantly greater degree than the Iowa DOT’ conventional methods of compacting the subsoil or adding topsoil. For more information, click here.
