The numbers are way off. It took around 10 years to get 4" of topsoil on my 80 acres of timber soil (clay). Not 1000 years.
And we have 111ft of that kind of soil here in Iowa. It going to take a hell of a long time to go through that. Its been farmed since the early 1800's. And not all gone, not by far.
I didn't read any further after that, maybe the article does have something to say. But I doubt it.
