Peter
Andrews is a stud master, and thoroughbred horse breeder and farmer
from Bylong in the Upper Hunter Valley. He is a man who many believe is
way ahead of his time. Peter has gained fundamental insights to the
natural functioning of the Australian landscape that leave him almost
without peer.
He has applied these insights
in restoring his and other properties to fertility levels that he says
existed upon European arrival in this country.
Over 30 years ago Peter, bought a run-down 2000 acre grazing property
called Tarwyn Park, near Bylong in the Upper Hunter Valley. He then
quietly set about testing the theories that he had been developing
virtually ever since he was a child, growing up on a station near
Broken Hill.
By
1976 Peter Andrews claimed that the model he had set up on Tarwyn Park
was an example of a sustainable agricultural system.
Peter had recognized that the incised nature of most streams in
Australia was in fact accelerating the fertility decline of
agricultural landscapes (Figure 1). Stream incision meant that the
increasing erosive energy of water was leading to accelerated soil and
nutrient loss, lowered capacity for the floodplain to hold water and a
loss of wetland habitat within that valley. Stream incision had in fact
lead to a total disruption of the natural fertility cycle, leading to a
chronic decline the overall health of the landscape. He also observed
that, under natural conditions, the interaction between fluvial and
biological processes would combine to maximise the efficiency of
nutrient and water use as well as carbon cycling.
He
argued that this would actually lead to a growing of that landscape as
sedimentation would far exceed erosion and carbon sequestration would
far exceed carbon loss.
