David Holmgren, one of the founders of Permaculture, used Yeoman's Keyline principle extensively in the formulation of Permaculture concepts and the design of sustainable human settlements and organic farms.
A topographical example can be seen on (37°09′33″S 144°15′08″E / 37.159154°S 144.252248°E / -37.159154; 144.252248).
Keyline also includes concepts for rapid soil fertility enhancement and these concepts are explored in Priority One by P. A. Yeomans' son Allan. Yeomans and his sons were also instrumental in the design and production of special plows and cultivating equipment for use in conjunction with the keyline methodology.
