Peter Davidson

Central / South SA & Western Vic Area Manager

0407 992 532 -

Originally from Keith in the upper south-east of South Australia, where I ran a mixed crop and livestock property. In 2009 I decided to seek new challenges that led to LawrieCo and Biological Farming with the role of field consultant. I find the work very rewarding and feel that I make a difference with sustainable and profitable agriculture.

Rodney Capon

Northern SA, NSW & Vic Area Manager

0409 822 011 -

Rodney is originally from Adelaide where he started out as a landscape gardener. He moved to the Sunraysia area in Northern Victoria / Southern New South Wales in the late 90s where he was involved in several large scale horticulture developments with a key focus on soil improvement and fertility. As part of his many roles he was involved in the importation and trials of humate plant and biological based soil conditioners. Rodney then entered into the nursery industry where he continued to learn the importance of soil carbon and soil biology. In the mid 2000s he changed direction and took control of a large dry land cropping / grazing property also comprising irrigation and some horticulture. Here he experimented with more humates and biological inoculants having outstanding results. He is excited to now be part of the Lawrie co team and looks forward to helping others gain the rewards of healthy soil.
