The Council for Agricultural Science and Technology (CAST) will release its newest publication, Precision Irrigation Management, during a live webinar. This paper explores how advanced irrigation technologies—such as variable-rate irrigation systems, soil and plant sensors, and evapotranspiration (ET)-based decision tools—are helping producers make every drop of water count. By integrating data, automation, and real-time monitoring, precision irrigation enables farmers to improve efficiency, reduce costs, and strengthen resilience to climate change.
