University of Georgia Smart Sensor Array (UGA SSA) for Scheduling Irrigation: New Developments

The University of Georgia Smart Sensor Array (UGA SSA) is a wireless soil moisture sensing system with a high density of sensor nodes which has been field tested for several years and will be commercially available on a limited scale in 2015.  This paper will describe the latest developments to the UGA SSA which includes a dedicated user interface from which users can view their data in multiple formats from any internet-capable device, an integrated irrigation scheduling decision support system, and the ability to wirelessly download daily prescription maps to VRI-enabled center pivot irrigation systems.  This paper will also present data on soil moisture variability in Georgia cotton fields as measured by the UGA SSA during the 2014 growing season.
