Thanks, DB. I would have liked to have seen what underneath looked like. Appears to be a bout the same setup I use, but with a rototiller. If I don’t plow first, the rototiller only digs down about four inches. I wouldn’t think that would put the unproductive soil on top, would you?
In the video it looks like he is spading over previous turned earth. I would have liked to have seen him spade over that vegetation.
