The main objective of this study is to develop a smartphone application for scheduling irrigation in soybean. The application, available for multiple smartphones, is called SmartIrrigation Soybean. It uses planting date, soil texture, irrigation type, and downloads local evapotranspiration and rainfall data, and uses this information in combination with the age of the crop to recommend when and how much irrigation should be applied to the field. The application obtains weather data either from a local weather station, gridded national weather data, rainfall predictive radar, or a local rain gauge located in the field. Results show it can greatly improve final crop yield, water use efficiency, and has the potential to improve on-farm profitability if used properly.
