Keyline methods enable the rapid development of deep biologically fertile soil by converting subsoil into living topsoil. Keyline pattern cultivation enables the rapid flood irrigation of undulating land without terracing. Incidental results are the healing of soil erosion, bio-adsorption of salinity and the long term storage of atmospheric carbon in the soil as humus. The Keyline Scale of Permanence provides a priority guide to planning the various factors of broad scale development. This is a recommended text for Permaculture students.
