Our Story

We Farm & Innovate

We farm ourselves and fully understand the benefits of precision surface drainage of agricultural fields. We were one of the first growers in the world to use laser levelling in sugarcane production starting back in the 1970s. It was a tremendous leap in technology enabling the transformation of basic land into highly efficient and very productive farming operations.  However, the problem with laser levelling is that you can shift up to 400% more soil than required. Apart from the much larger earthmoving cost that this involves, it also disturbs a lot more topsoil which can have significant impacts on crop yields for decades. We continue to develop our own sugarcane farms and saw the opportunity that GPS machine control offered in solving these limitations of laser levelling. So in the late 1990s, we set about coming up with a system that took full advantage of this new technology. That is what we call Optimum Surface Landforming™ or OptiSurface™.

Our Vision

10 million hectares (25 million acres) of agricultural land with improved drainage or irrigation feeding over 10 million people more than it was previously.

Our Mission

OptiSurface™ is the world's leading solution for agricultural earthworks design, providing our customers with the most valuable analysis and design services and software to meet their needs.

What We Do

For leading farmers, agricultural consultants and earthmoving contractors who want to improve farm profitability through improved water management, OptiSurface Designer is the worlds most powerful analysis and design software for agricultural landforming. It calculates the optimised field topography that satisfies water management goals whilst minimising earthworks and without ditches. It does this using our patented system incorporating Continuously Variable Grades™ (CVG™) along with 3D GPS machine control technology.

Executive Team

Graeme Cox, PhD BEng Ag (Hon)

Graeme is the Engineering Director for DAVCO Farming. He is an Agricultural Engineer, graduating in 1996 with first class honours. He also earned his Ph.D. in Sugar Cane Precision Agriculture from the University of Southern Queensland in 2002. He has over 12 years experience as a consulting engineer in the fields of farm irrigation design, water engineering, hydrology and flooding. His research and extensive background were instrumental in developing the patented OptiSurface system.

David Cox

David is the Principal of DAVCO Farming in Ayr, Queensland, Australia, which one of Australia's largest private sugar cane producer, growing over 250,000 tonnes per year. He has over 40 years of practical experience in farm design and development with a significant focus on landforming (land leveling). He was a early adopter of laser grading in the 1970s and the first to apply precision agriculture to sugar cane including yield mapping, precision GPS machinery guidance, GPS weed mapping and GPS variable rate application.
