This article is a critique of keyline subsoil plowing for the purpose of soil building (exclusively) written by agronomist Rachel Gilker. The comments are particularily interesting, and there is debate about how the study was conducted. In these studies, soil moisture content was not evaluated, something we hypothesize could improve following keyline pattern subsoiling on sloped landscapes. One thing is clear, keyline subsoiling must be coupled with other soil building practices to be most effective.
