OptiSurface - Optimum Surface Landforming PowerPoint PPT Presentation


Eighty percent of crop yield loss within a field and within years can often be attributed to variable moisture availability, both too little and too much. Excess moisture also plays havoc with machinery operations and farm efficiency. By improving surface drainage and promoting more uniform infiltration, Optimum Surface Landforming has shown to provide a range of profit boosting benefits at a relatively low cost per hectare resulting in a high Return On Investment (ROI).

Evolution of Landforming

We have been landforming since agriculture began


Evolution of Landforming

  • 1900s Dumpy & Stakes

  • 1970s Laserplane

  • 1990s Multiplane

  • 2000s OptiSurface*

Benefits of Landforming

  • Higher Yields, Quality and Profit through

    • Minimised water logging

    • Improve infiltration uniformity

    • Sooner trafficability

    • Improved crop establishment

    • Improved uniformity of crop maturity

    • Reduced weed problems


OptiSurface Landforming

  • …provides all of the benefits of traditional laser landforming only:

MUCH BETTER!!

  • Much cheaper (up to 80%)

  • Much less topsoil removal

  • Much faster

  • Block: C7 Area: 92 Ha

  • Location: DAVCO Farming, Burdekin

  • Row Cropping (sugar cane)

  • Lateral Move Irrigation

Design Surface Options

  • OptiSurface 1D

    Row drainage in one direction only

  • OptiSurface 2D

    Row drainage in two directions

  • OptiSurface 4D

    Can drain in any direction as long as it leaves the field
