Resilient Human Settlements by Design

El Manzano Permaculture does Regenerative Design. We create beautiful & resilient human settlements that restore ecology, strengthen community, and stimulate local economy. We can handle every aspect of landuse projects, from initial project creation to design, planning, implementation and ongoing maintenance.

Established in 2007 AppleTree Permaculture is a recognised market leader working at the forefront of innovative and sustainable land-use strategies, urban design, and landscape development in Chile.

We are a collaborative team of landscape designers, ecologists, rural planners,

Eugenio Gras: “Soil & Water Harvesting: Design with Permacultura & Keyline”

A Regenerative Design Pioneer in México

By Holger Hieronimi, Abril 2010 published in Linea Clave Mexico.

We can celebrate the first book published in Mexico since 1998, which makes direct reference to the concept of permaculture! So far, the collection of Alejandra Caballero (1) stands as the only title that incorporates the experiences at home. COAS now gives us this new publication entitled "Soil and Water Harvesting - Design with Permaculture and Keyline.

Its author is Eugene Gras, a pioneer of organic agriculture in Mexico and regenerative design. In summer 1995, Eugenio connected me with some of the first facilitators who at that time taught permaculture courses in the country (2). Shortly after he left for Australia, in order to deepen their knowledge (although there were few teachers and designers with

Soil Carbon & Moisture in Mediterranean Climates

Experience from Cristine Jones

In addition to enhancing nutrient availability, carbon performs many other functions in soil, including the maintenance of soil porosity, aeration and water-holding capacity.

Glenn Morris (Morris 2004) extensively researched the water holding capacity of humus (an extremely stable form of soil carbon) and concluded that within the soil matrix, one part of soil humus could, on average, retain a minimum of four parts of soil water.

From this relationship it can be calculated that an increase of 16.8 litres (almost two buckets) of extra plant available water could be stored per square metre in the top 30 cm (12”) of soil with a bulk density of 1.4 g/cm3, for every 1% increase (in absolute terms) in the level of soil organic carbon.

AGRICULTURAL LIBRARY

Here you can find an extensive list of publications on agricultural practice including this classic from Yeomans.

Percival Alfred Yeomans (P.A.) was born in Harden N.S.W. in 1905, eldest son of a family of four. In 1928 he married Rita Irene May Barnes, also of Harden. They had three children; Neville born in 1928, Allan in 1931 and Ken in 1947. Rita Yeomans died 1964 and the two original Keyline properties at North Richmond N.S.W. were sold to pay death duties.

P. A. Yeomans married Jane Radek in 1966 and they had two daughters, Julie and Wendy. Following this marriage he undertook the design and construction of a different concept in cultivation equipment. He solved the need for better equipment than the chisel plow to deeply loosen soil without bringing up the subsoil. This equipment was the first rigid shanked vibrating sub-soil cultivating ripper for use with farm tractors. It is many times more efficient than a chisel plow, and is able to loosen more soil to a greater depth using less tractor power.

The Prince Philip Design Award officially recognised the breakthrough success of this equipment in 1974 when P. A. Yeomans Pty Ltd received this coveted award for the Bunyip Slipper Imp with Shakaerator.

Manufacture of the Bunyip Slipper Imp eventually passed from P. A. Yeomans Pty Ltd to the Yeomans Plow Company, which is now based at Molendinar in South-east Queensland. This company is owned and directed by Allan J. Yeomans the second son of P. A. Yeomans. The equipment has undergone further developed including some landmark design breakthroughs and has been renamed the Yeomans Keyline Plow.
