Regrarians co-founder Darren Doherty builds a scale model watershed to explain how water cycles through the landscape in a sequence of natural patterns.
A seminal text by Keyline developer P.A. Yeoman. Free online version.
A classic short film that traces keyline design back to its roots on P.A. Yeoman’s farm. Since this time, many technological advances like poly-irrigation tube and moveable electric fencing have revolutionaized regenerative farming, however, the keyline patterns remain the same.
A concise article providing a good introduction to keyline design, written by Abe Collins and Darren Doherty.
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.
