We used milk, Sea-Crop, planned grazing of livestock herds and Keyline subsoil plowing. The combined inputs/management had the effect of converting subsoil to topsoil at about 8" per year in 2008. Pretty exciting! Not very scientific information, but compelling enough to warrant some real research.
