verb
scarify
SKAIR-uh-fye/ˈskerɪfaɪ/
To make shallow cuts across a surface.
The tool scarifies the compacted soil with shallow parallel cuts.

Etymology
The underlying action is scratching a surface open. Early English use referred to shallow cuts made in the body to release blood or pus—the same surface-cutting action expressed in the soil sense.
In context
