Drones have increased in popularity among no-tillers the last decade, but their return on investment is not yet proven, as researchers continue to test the technology in many different applications, such as cover crop seeding

Unmanned aerial vehicles (UAVs) are known in popular culture as “drones.” They can cover hundreds of acres in an hour and provide a birds-eye view of fields at the canopy level.

Working with a team, Purdue University professor of weed science Bryan Young decided to test UAV use after hearing positive testimonials and advertisements about fertilizer drone applications. There were some promising results but also challenges along the way. 

There are several operational differences for growers to consider when switching from a ground rig to a drone. UAVs could potentially reduce pesticide waste overall — depending on how well growers use their alternative application systems — by being more precise and intentional with their applications. 

Battery-powered drones can spot spray sections of a harvest, allowing growers to note what is needed from an aerial point of view and adjust the nozzles to the droplet size needed in real time.
