‘Soil, Water & Carbon for Every Farm’ – Building Soils, Harvesting Rainwater, Storing Carbon
by Abe Collins & Darren Doherty
Introduction
Keyline Design was first developed by the great Australian, P.A. Yeomans (1904-1984), in the late 1940s & 50s initially as a practical response to the unpredictable rainfall regime he found on his new property, ‘Nevallan’, to the west of Sydney, New South Wales, Australia. Soil Conservation, as developed by the US Army Corp of Engineers was the predominant practice of the time and for a time Yeomans was influenced by this, though soon found some deficiencies with the pattern of water flow its application expressed. Yeomans went on to devote the rest of his life to the promotion, research and development of Keyline Design and in doing so was labelled by Permaculture co-originator Bill Mollison as "…one of Australia’s greatest patriots… ".
Influenced by the likes of prominent organic agriculture figures in Andre Voison, Friend Sykes, Newman Turner & Louis Bromfield (among many others!) Yeomans has been attributed with being the 1st person to accelerate soil formation through the stacking of methods, overturning the myth that it took 1,000 years to create an inch of topsoil. Yeomans proclaimed that "…the landman’s job is not so much to conserve soil as it is to develop soil, to improve his soil and to make it more fertile than it ever was…".

Vetiver Grass – A Hedge Against Erosion
Food Plants - Perennial, Land, Plant Systems, Rehabilitation, Soil Erosion & Contamination, Terraces — by Richard Webb
PIJ #54, March – May 1995
Soil erosion is perhaps the world’s most chronic environmental problem that is literally costing the earth. The soil it carries off now totals 20 billion tons a year and this loss is not only severely degrading the environment, it is eroding the economic viability of countries. Despite enormous effort, standard soil conservation methods have been largely unsuccessful. However, a remarkable tropical grass may hold the key to a cheap, practical solution for controlling soil erosion on a huge scale in tropical and semi-arid regions. It also has many attributes that make it useful to farmers.
Vetiver (Vetiveria zizanoides) is a densely tufted, perennial clump grass with stiff leaf bases which overlap.

Making Contour Maps on the Cheap

 An example of the results Click for larger view |
I developed a technique last year during the Keyline Design Course at Tuscon, Arizona for making a contour map using cheap available materials. One of our students didn’t have the cash to get a surveyor to do the job on his 40 acres, so I came up with this solution on the whiteboard and have since tested it on the ground quite a few times now.
