How is Contour Scarification Performed?
Small tractors, bulldozers, or all-terrain vehicles are fitted with a tool bar containing tines, rippers, or other devices capable of loosening and mixing the soil to a depth of two to four inches. A contour line is marked about one-third the way down the slope to establish a key line. The machines are operated parallel to the key line. The entire slope may be scarified to accomplish the maximum effect. To reduce treatment costs, contour scarification can be accomplished in eight- to 10-foot-wide strips spaced uniformly over the slope. The maximum recommended spacing between scarified strips is shown below.
