Precision Weed Control with Thermal Micro-Jetting
40x labor advantage in vegetable crops with robotic micro-spray technology
Tensorfield Agriculture is pioneering the commercial adoption of thermal micro-jetting for weed control and thinning in vegetable crops. Based on research from the University of California, Davis and the University of Bonn-Landtechnik, we eradicate weeds using only superheated vegetable oil.
Our machines operate semi-autonomously, with a continuous 232 nozzle array treating one 80-inch bed at 1.2 mph with 1/4 inch precision. By design, travel speed is independent of weed pressure, and each nozzle array covers 1 acre per hour whether there’s 50,000 weeds per acre or 500,000.
We’re starting with trials in carrots, spinach, lettuce and more on the West Coast of the US.
Contact us to arrange a trial.
No Soil Disturbance
We don’t break the soil crust, effective in all soil types without damaging your keeper crops
1/4 Inch Precision
Our thermal-micro dosing sprayer enables us to kill weeds in densely planted beds with 1/4 inch precision
Organic Approved
We use only heated vegetable oil to kill weeds – no extensive herbicide inventory required
