Waste from sugar production can remove harmful pesticides from the water.
Meanwhile, a Swiss-based startup has developed a new smart system for the farming industry which limits their use in the first place. The team’s precision field sprayer reduces the use of pesticides by up to 95%.
Cameras mounted on the device scan the field sections underneath while driving, with AI analysing resulting images to differentiate between weeds and crops.
Only the exact amount of pesticide needed is sprayed on each weed, by whichever of the 156 spray nozzles is closest to it. A tablet lets tractor drivers control crop specific programs.
Others are deploying laser robots for weeding or using abandoned barns for vertical farming.
