Qu’est-ce que le Keyline Design ? Éléments de base pour débuter.

Keyline Design is a land and water management approach developed by P.A. Yeomans in the 1950s. It uses topography to optimise water distribution, reduce erosion, and enhance soil health. By identifying “keypoints” in valleys and drawing gently sloped “keylines” towards ridges, the method redirects runoff to improve infiltration and resilience. A central tool is the Yeomans Plough, which aerates the soil without inverting it. Keyline Design promotes sustainable agriculture through more effective use of natural resources.
