Compost/Erosion Research and Demonstration Project

Project Description
The objectives of the Compost/Erosion Research and Demonstration
Project (CERDP) are:

1. Measure and compare the quantity and quality of roadside vegetation
(grasses) grown on conventionally treated roadway foreslopes with
vegetation produced on foreslopes amended with various levels of
three types of composted organics produced in Iowa.

2. Measure and compare soil characteristics, runoff quantity, and
soil erosion occurring on conventionally-treated roadway foreslopes
with that occurring on foreslopes treated with composted organics.

3. Use field measurements of soil erosion to calculate interrill and
rill soil erodibility factors that can be used with the USDA Water
Erosion Prediction Program to model and predict the effects of compost.
