Evolution of Landforming We have been landforming since agriculture began optisurface. com

Evolution of Landforming – 1900 s Dumpy & Stakes – 1970 s Laserplane – 1990 s Multiplane – 2000 s Opti. Surface* *Patent Pending optisurface. com

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. com

Opti. Surface Landforming …provides all of the benefits of traditional laser landforming only: MUCH BETTER!! • Much cheaper (up to 80%) • Much less topsoil removal • Much faster optisurface. com
