Soil Erosion Control for Secondary Roads, HR-155

Research project HR-155 was initiated to study soil erosion problems along the secondary road system in Iowa and to find a substitute for straw for the control of soil erosion during the period of seed establishment. Accordingly, six field research sites were established to test the ability of commercial soil conditioners to control soil erosion. The six field research sites were selected on the basis of terrain and type of soil material exposed on the cut-slope areas.

Roadside erosion research in selected Iowa counties, 1972

This research project discusses roadside stabilization along secondary roads. Another objective was to investigate various commercial soil stabilizers, as a replacement for straw mulch, to control soil erosion before vegetation.
