DUBUQUE — Unmanned aerial vehicles, famous for delivering lethal strikes on terrorists, have yet to live up to their considerable promise for improving farm productivity.
“They have the potential to gather and process an unprecedented amount of data, but that data must be actionable — it must provide information that guides farmers to specific actions that increase yields,” said John Deere robotics manager Stewart Moorehead, the keynote speaker at a recent conference in Dubuque titled Unmanned Systems and Agriculture.
Although the industry is in its infancy and hobbled by the lack of specific government regulations, it has a bright future, according to Moorehead and other speakers at the March 4 conference in Dubuque.
Drones — or unmanned aerial vehicles or systems, as their adherents prefer to call them — are ideally suited for scouting crop fields during the growing season, covering hundreds of acres in the time a human observer could walk but a few.
“You can also see patterns from the air that you can’t see from the ground,” said Brad Buchanan, owner of Cedar Rapids-based Crop Tech Services, which started using drones last year to supplement its traditional crop-scouting services.
In addition to standard images and video, cameras can capture enhanced images — infrared, thermal and NDVI (normalized difference vegetation index) — that provide insights into soil conditions and plant health.
“Right now, as the proposed rules stand, the use of drones is very limited beyond capturing images,” said Chris Draper, director of EMERGE, an entrepreneurial development initiative at Simpson College in Indianola.
The 55-pound weight limit, which precludes most chemical applications, and the requirement that operators keep the drones in sight are among the chief limitations, said Draper, a former employee of the Federal Aviation Administration, the agency that regulates drones.
Once the rules have been well established, drones will play an expanded role in agriculture, he said. But until the FAA issues formal rules governing commercial drone use — which many expect later this year — commercial operators are required to secure a Section 333 exemption.
