National Trust brings in robot to map weeds on farm
A National Trust estate has brought in a robot to map the location of weeds in a bid to cut chemical use and improve environmental performance.
It will allow farmers to apply herbicides solely to areas where there are weeds rather than spraying large areas.
Two further robots are in development, one to zap weeds with an electrical charge and the other for precision planting.
It is hoped that the zapping robot will remove the need to use chemical weedkillers, which harm biodiversity.
