Technical Abstract: Precision irrigation management is greatly aided by tools that fortunately are becoming increasingly low cost and easy to use. A large and diverse ecosystem of providers of technology and inputs is now present in the marketplace, making adoption of precision methods easier, but complicating the decision making process for farmers. Several tools can help a farmer know when, where and how much to irrigate. These include new, lower-cost soil water sensors, infrared thermometers for assessing crop water stress (crops become warmer as they become water stressed), and wireless data telemetry systems that are increasingly available, low cost and place field data directly on the Internet where a farmer can easily access it. Pressurized irrigation systems, such as the drip irrigation systems that serve >95% of Jordan Valley irrigated lands, allow control over where and when water is applied. Increasingly, control systems are available that can turn irrigation valves on and off automatically or through remote control using radio and cellular systems. New decision support systems automate crop and soil water stress sensing systems, and apply algorithms to the data that result in irrigation decision recommendations.
