Precision agriculture improves water efficiency and crop yields

A two-year study conducted by researchers at the University of Bari Aldo Moro in Puglia, Italy, has demonstrated that precision agriculture can significantly improve water efficiency and crop yields. Using soil-water sensors, automated irrigation, drone surveys, and near-infrared spectroscopy, the study found that sensor-guided irrigation reduced water use by approximately 15% in processing-tomato fields while producing higher marketable yields compared to traditional farmer-managed plots.

In table grape cultivation, the same precision approach reduced irrigation by 8% to 15% and maintained steadier plant water status. The technology relies on continuous soil measurements to trigger irrigation at specific thresholds, rather than relying on visual estimates of crop needs.

Complementary developments in agricultural technology include the adaptation of fiber-optic communications for precision irrigation. Originally designed for telecommunications, this technology can provide low-power communication in structured agricultural environments to support smarter water management. Experts note that while technical innovations like these are vital, a significant challenge remains in the ‘missing middle’—the gap between laboratory research and the commercial scaling of these technologies to achieve real-world impact.
