Davco Farming completed 800ha (2000acres) of Optisurface Landforming in 2009 on 'Oaky' in North Queensland, Australia.

The area is made up of 9 fields of approximately 88ha each which will be irrigated by lateral move and/or subsurface drip irrigation. The design surfaces are made up of OptiSurface 1D (single direction drainage) and OptiSurface 2D (two direction drainage). The field will grow sugar cane using the Davco Precision Farming System. The image below is an example of a OptiSurface 1D design, shown in 3D perspective view.
