Water for Every Farm : Yeomans Keyline Plans - P.A. Yeomans
Keyline is a set of principles, techniques and systems, which form the logical basis for a practical plan for the sustainable development of rural and urban landscapes.
The first book on Keyline book was published in 1954. In it, P.A. Yeomans exploded the myth that it takes 1,000 years to produce an inch of topsoil. Yeomans pioneered, among other things, the use of on farm irrigation dams in Australia, as well as chisel plows and subsoil aerating rippers. Yeomans perfected a system of amplified contour ripping that controlled rainfall run off and enabled the fast flood irrigation of undulating land without the need for terracing.
