Technical Abstract: As irrigated agriculture faces uncertainty and limited water resources, managing water under limited irrigation becomes increasingly important. Detecting crop water stress, both over time and space, is challenging but possible using infrared thermometry to measure canopy temperature. In this talk we discuss an ongoing experiment at the Limited Irrigation Research Farm near Greeley, CO, where canopy temperature is used as an indicator to both trigger irrigation and quantify crop consumptive use. This technology has potential to be scaled spatially to inform variable rate irrigation systems.
