Weed control using robots
|
|
|
|
A Danish robot, is undergoing trials at the moment, that maps the position of weeds growing among crops using differential GPS. It is hoped that a later version of the robot will also selectively spray these mapped weeds using only a few drops of herbicide. However the longer-term goal is to avoid herbicides altogether by having the robot pull the weeds out of the ground rather than killing them.
In tests, carried out on fields of sugar beet, the scientists at Aalborg University have found that selectively sprayed weeds identified by robots reduces overall herbicide use by 70 percent. However because herbicide is so cheap that even reducing its cost by that amount will not make much of an impact on farmers, but the goal of the scientists is to reduce the effect of herbicide's on the environment.
