This general planning takes further pattern according to the water relationship of the farming enterprise. If water is scarce and the limiting factor, the plan provides the ultimate in efficiency in the conservation of water. The Keyline plan is designed to be economical. Planning not only protects land from floods, but turns flood water to advantage. Planning beats drought very easily.
Planning protects land from fire.
I have not seen any good property that Keyline would not improve threefold, with the exception of the smaller properties which sometimes reach close to the maximum of production by means other than the best or most economical. The general order of potential improvement on most grazing properties in Australia would be from three to ten fold and more. These start with the smallest or primary valleys which flow into other larger valleys. The primary and secondary valleys are those of the farms and grazing properties. Of these two, the primary valley is of the greatest significance.
