What would you be willing to accept as proof? Is observation by me (not a
soil scientist) proof? Is observation by a soil scientist proof? If not
observation then what? By observation I mean, look at soil loss when the
soil is compacted vs looking at soil loss when loosened, such as what
happens when holes are poked in it with poles.
