Smartirrigation Apps: Urban Turf

Haimanote K. Bayabil, K. W. Migliaccio, J. H. Debastiani Andreis, C. Fraisse, K. T. Morgan, and G. Vellidis

As freshwater resources become increasingly scarce, efficient irrigation scheduling methods that allow efficient irrigation water uses are required. Migliaccio et al. (2016) have developed an app called Smartirrigation Turf, an easy-to-use mobile tool that delivers information to improve irrigation scheduling for urban turf. The app was only available for Florida and Georgia, but recently, we have made improvements to the app and made it available to any location throughout the contiguous United States.

Selecting a Method for Sealing Ponds in Florida

Dorota Z. Haman, Fedro S. Zazueta, Gary A. Clark, Sandra Guzman, and Haimanote Bayabil

A pond can be created by constructing a dam or embank- ment across a watercourse, by excavating a pit or dugout, or by building a dike around a natural depression area. For many farms, ponds may be the most economical way to provide water for various agricultural operations. Necessary water for irrigation, livestock or fish production, or other purposes can be stored in the pond. Ponds can also be used to store runoff from irrigation or rainfall events. The use of this surface resource could lead to reduced pumping from deep aquifer water  supplies.
