“Keyline planning is based fundamentally on the natural topography of the land. It uses the form and shape of the land to determine the layout and position of farm dams, irrigation areas, roads, fences, farm buildings and tree lines. Today, Keyline topographical concepts are often taught in university town planning courses.”( Yeomans Plow, 2020)
“Keyline is an agricultural system in which great emphasis is placed on processes designed to increase substantially the fertility of soils. Emphasis is placed on the creation of a soil environment that rapidly accelerates soil biological activity, thus vastly increasing the total organic matter content within the soil.”( Yeomans Plow, 2020)
