UAVs for Agricultural Weed Control

  • Rating12345

Precision Agriculture is a hot topic these days as researchers look for ways to reduce the massive amounts of chemicals that are currently sprayed on food crops. A new research paper describes one of the ways robots may help in Early Season Site-Specific Weed Management (ESSWM). In the study, a UAV equipped with a multispectral camera collected images of sunflower field infested with naturally occurring weeds. Similar imaging techniques using traditional satellite and aerial methods to adjust herbicide distribution have yielded up to 50% reduction in the total amounts of herbicides used. The researchers hope to replicate this process using the less expensive flying robot. Read More
