Opinion: Drone regulations ground valuable farming technology

Unmanned aerial vehicles — drones — are a part of many farm futures. From field and pasture reconnaissance to application of pesticides, the ability to see land without setting foot on it offers many advantages that can improve the bottom line.

Technology is developing faster than the regulations that guide operations, as is usually the case, so there’s a risk that producers will put the tools to work before the rules are ready. Liability issues are only some of the negative effects possible should accidents occur ahead of regulation. Guidelines are needed that encourage UAV use rather than stifle it.

Current aerial regulations weren’t designed for larger, utility machines that work on their own. Today’s rules were aimed at tiny machines that pose little peril when kept away from larger aircraft and from humans on the ground. And even those are evolving as the technology improves.

Field Talk Friday | Dr. John Murphy | Root Exudates, Soil Biology, and How Plants Recruit Microbes

Most of us spend our time managing what we can see above ground—plant height, leaf color, stand counts, and yield potential. But the deeper you dig into agronomy, the more you realize that some of the most important processes driving crop performance are happening just millimeters below the surface.

In this episode of Field Talk Friday, Dr. John Murphy continues the soil biology series by diving into one of the most fascinating topics in modern agronomy: root exudates and the role they play in shaping the microbial world around plant roots.

Roots are not passive structures simply pulling nutrients out of the soil. They are active participants in the underground ecosystem. Plants constantly release compounds into the soil—sugars, amino acids, organic acids, and other molecules—that act as both energy sources and signals for soil microbes.
