Deciding Your Plow Configuration

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.

An Academic’s Keyline Assessment

Creating Fertility. Locating Keylines

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.

The Subsoil Plow Story

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".

Video Library

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.

Yeomans Keyline Systems Explained

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.

“Carbon Still” Soil Test System

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.

Cheap Solar Thermal Electricity

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.
