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).

Benefits of landforming

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

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
