The Keyline Plow
The RED BOOK is a booklet with pictures illustrating the variety of plows we make and the range of points and components that can go with them.
How many horse power per tine (or shank or leg). Whether a three point linkage plow or a trailing model. Size of tines to suit. And other things to ponder and decide on.
When do I first use it. What's a suitable speed. How deep should I go. What points to use. Do I need coulters. And lots of other things it's nice to know.
The late Professor J. MacDonald-Holmes was Dean of the Faculty of Geography, University of Sydney and a truly great Australian. He followed the development of P.A Yeomans' Keyline principles from their inception in the late 1940s.
Allan Yeomans describes, in basic terms what fertile soil really is and why it is possible and practical to massively enhance the fertility levels of farm soil. Also here, is a description of valley forms and where the Keyline is, and why and how it works. And how to find it.
Keyline cultivation required a plough that didn't turn the soil layers upside down. We looked everywhere. The Texas made Graham-Hoeme Chisel Plow was the only thing we could find available anywhere in the world. We got one and used it, and then made them under license. And sold them here in Australia in the thousands. And that's why I still spell it "plow".
A collection of relevant plow and Keyline footage and links to YouTube. Some filmed in the 1950s. Others by Darren Doherty, a long time friend of mine and a Keyline and Permaculture guru. The Keyline concepts of farm planning, water storage and handling, accelerated soil fertility enhancement and rotational grazing, were developed on our family farms in the early 1950s. In the 1980s, by combining these experiences with gliding meteorology I conceived the concept of enhancing soil fertility to stop global warming. Allan Yeomans 2016
The Keyline system has changed only slightly from my father, P.A, Yeomans' original books on Keyline. The main change started in the late 1960s with our work on developing a ripper with almost zero disturbance of soil layer profiles. The modern subsoiler was born and highly accelerated Keyline soil fertility enhancement became possible and practical.

To end Climate Change we pay our farmers $10 a tonne - carbon dioxide equivalent - for increasing the carbon content of their soils. The best and most consistent measuring process for measuring this carbon increase is by measuring the Loss On Ignition (LOI) of a representative sample of the soil. Our 'Carbon Still' does the measuring.
The only significant factors in determining the sale price of the power produced from a solar thermal installation is the cost to cover deprecation and the amount of interest on the money used to build it. That's where our Yeomans system out shines them all.
