Irrigation scheduling is a critical tool to successfully managing irrigation on crops while maximizing Irrigation Water Use Efficiency, and in some cases increasing quality and yield. Most producers based on national surveys are currently scheduling irrigation via visible stress, however, by this point the crop has already lost yield. The goal of this presentation is to provide insights on how a large scale irrigation scheduling project has been implemented in the state of Georgia, the responses to the project and improvements that can be made. This presentation is focused on Georgia, but is applicable across most of the U.S. Specifically this presentation will provide insights as how to decide on sensor types, how to select where to place the sensors within the field, and how to look at data from the sensors. This presentation also provides information on what producers should consider when adopting soil moisture sensor systems.
