Precision Agriculture and Irrigation: Current U.S. Perspectives

Highlights. Precision agriculture (PA) applications in irrigation are stymied by lack of decision support systems. Modern PA relies on sensor systems and near real-time feedback for irrigation decision support and control. Sophisticated understanding of biophysics and biological systems now guides site-specific irrigation. The internet of things (IOT) enables new ways to increase yield per unit of water used and nutrient use efficiency.
