Evolution of Landforming
We have been landforming since agriculture began
optisurface.com
Evolution of Landforming – 1900s Dumpy & Stakes
– 1970s Laserplane
– 1990s Multiplane
– 2000s OptiSurface**Patent Pending

Benefits of LandformingHigher 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
MUCH BETTER!!
…provides all of the benefits of traditional laser landforming only:
• Much cheaper (up to 80%)• Much less topsoil removal • Much faster
