South Dakota State University researchers are using advanced technology to improve farming and ranching across the state. Their work focuses on helping producers reduce labor, lower costs, improve efficiency, and protect natural resources through modern agricultural tools.
Researchers at SDSU are studying virtual fencing systems for cattle management. Assistant professor Hector Menendez demonstrates how ranchers can move cattle by using GPS collars and a mobile application instead of physical fencing. “It's a pretty easy application to use,” Menendez said. “The technology will guide the animals to their new pasture.”
The virtual fencing system uses satellite signals and wireless communication to create grazing boundaries. When cattle approach a boundary, the collars send warning sounds and mild stimulation to guide the animals back into the pasture area. Researchers find that this system supports rotational grazing while reducing fencing costs and labor needs.
Studies at Cottonwood Field Station show that virtual fencing does not reduce livestock performance. Researchers report similar weight gain, feed intake, and carcass quality compared to traditional grazing systems. The technology also helps ranchers monitor animals remotely and improve work-life balance.
SDSU researchers are also using remote weighing systems to collect cattle weight data directly from pastures. These systems help producers monitor animal health and nutrition while reducing stress on livestock. Artificial intelligence combines this information with weather and grazing data to support better farm decisions.
Drone technology is another important area of research. SDSU teams are developing drones equipped with cameras, sensors, and AI-powered systems to identify weeds and spray herbicides only where needed. This targeted spraying method helps reduce chemical use, lower production costs, and improve soil and water quality.
Researchers explained that drones can also monitor crop health, irrigation needs, pests, and diseases using multispectral imaging systems. The collected data allows producers to detect crop problems earlier and respond more quickly.
