The concept of precision agriculture, or the use of data to enhance agricultural production, has been around for more than two decades. The field includes a range of different technologies, including GPS-guided tractors, yield and soil monitoring, variable rate applications for water and fertilizers, and data collection by satellites and unmanned aerial vehicles. Technology in agriculture will enable farmers to do more with less — especially as advances in sensor technology and computing technology continue — to keep up with rising demand for agricultural products over the next few decades. Using even one of the precision agriculture technologies can save farmers substantially on a per-acre basis. Giving Farmers an Eye in the Sky The U.S. Federal Aviation Administration has issued new regulations, effective Aug. 29, governing the use of unmanned aerial vehicles in the United States.
