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.

Yorke Peninsula, Wimmera and Southern Malleee Area Manager

Bill Greenslade, LawrieCo Area Manager0438 159 656

Bill has had wide ranging experience over 30 years in the rural industry which covers key areas such as agronomy and marketing. Much of Bill’s work has been within the fertiliser industry having had time in both retail and wholesale businesses.

Bill’s sound knowledge of nutrition and soil science complements the practical application of fertiliser programs in the field, particularly biological and carbon-based products as well as trace elements.

He sees “one of the big challenges for the Australian grain industry is maintaining quality, particularly wheat protein. Over 30 years, soil nitrogen profiles have been in significant decline as productivity increase and rotations tighten.”

In today’s farming systems, he works with producers to make every post a winner, in-regards to gaining maximum benefit from applied nutrients as well as building general soil health. “Applying more was better” was the thought process in his early days as an agronomist, nowadays efficiency is the aim and environmental responsibilities are considered.  This comes from soil health and the nutrient holding and releasing capacity of our soils.

Bill understands biologicals are an emerging space and there is still a lot to be learnt, he works toward paddock truthing and the sees the effective application is becoming easier, so rates and frequencies are increasing. He sees long term opportunities as the carbon economy develops, opening up new markets and highlights the strong link to soil health as a key driver in developing farmer participation in these offsets.

Bill is based in Bordertown, which is central to SA and Victoria’s major cropping, livestock and horticultural regions and looks forward to servicing the resellers, agronomists and growers within his area.
