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.
EL GRANJA FAMILIAR
THE FAMILY FARM
Yeomans and the City Forest.
If my analysis of the landscape design of Nature; of soil and landscape processes, and of the bastardisation of agriculture, are correct; the only answer to the depravity and destruction of our environment and for the consequent inhumanity of society is a re-union of mankind with the natural landscape and the ways of Nature.
Firstly, it is proposed that the City Forest be the major step for the cities; secondly; all country towns should be redesigned to include their own City Forest in preparation for increased population, and thirdly, there is THE FAMILY FARM, and the redesign of the whole farming landscape. Fourthly is the need for the creation of new cities.
