Apps in Agriculture: Perfecting the New Avocado Smart Irrigation App

One of the newest additions among the SmartIrrigation Apps to be released by UF IFAS is for avocado. Commercial production of avocados in Florida is primarily centered in Miami-Dade County - approximately 7,400 acres (Fig. 1). Read more about avocados in this EDIS article.

Bells and whistles
The avocado smart irrigation app has some special features to accommodate for the different varieties and needs of avocado growers in Florida. One unique feature is an emailed output with irrigation scheduling information (Fig. 2).

Further, the app can be used with overhead solid set and microsprinkler irrigation systems. Microsprinklers provide targeted irrigation which is more efficient than solid set (Fig. 3). However, many growers use solid set not only for irrigation but also for cold protection (Fig. 4).

The app uses real-time FAWN data for determining the irrigation schedules (Fig. 5).

In trial phase
We are currently testing the app at the UF IFAS Tropical Research and Education Center and on a local grower’s field in Homestead, FL. Anyone interested in being an app tester should contact Dr. Kati Migliaccio ( The app is slated for release in April 2015.

This project is being conducted by Dr. Migliaccio’s group. Mr. Deanroy Mbabazi is leading this effort as part of his MS research.
