SmartIrrigation Avocado was developed by the University of Florida and operates on iOS and Android platforms. The app determines an evapotranspiration (ET)-based irrigation schedule using crop evapotranspiration (ETc), irrigation systems characteristics, soil characteristics, and root depth.
Weather data from the Florida Automated Weather Network (FAWN) are automatically downloaded from a station in the network close to the field locations or from a station assigned by the user.
The SmartIrrigation Avocado app generates a 15-day irrigation schedule based on the previous five days of ETc calculations. This schedule is updated any time there is a 50% or greater change in the average ETo for the previous five days.
