Our Goals Interactive ET‐based irrigation scheduling tools
Operate on a smartphone platform
Can be used to implement both conventional and precision irrigation across Florida and Georgia
Cost producers only a few dollars per year provided they have a smartphone
Minimum user input
Ready‐to‐use output
Engaging – not static
Meteorological DataCrop coefficient approach for estimated ET
where
ETc = estimated crop ET
Kc = crop coefficient
ETo = Penman‐Monteith reference ET (FAO‐56)

Turf• Notifications of rainfall and forecasted events
PrecipitationCitrus
• Irrigation delay based on rainfall depth
Cotton• Provided by station but modified
by grower
Strawberry• Not included; plastic mulch with
irrigation everyday
Irrigation Systems Citrus Micro‐sprinkler
Cotton Center Pivot, Drip
Strawberry Plasticulture Drip
Turf Pop‐up Heads
Apps require system characteristics
Soil Water Holding Capacity
Soils represented by standard classes (clay, sand, etc.) and/or local soil names (Gladeland, Krome)• NRCS data
Field capacity and wilting point boundaries used
No irrigation schedule recommendation exceeds water holding capacity
Select the soil type which best represents your
field.
Irrigation Schedules
For Citrus, Strawberry, and Turf only
Average ET of previous 5 days
Updated every 15 days unless ET changes are >50%

App Performance
2013 – Evaluated at Stripling Irrigation Research Park (SIRP) Replicated plot studies, one variety July and August wetter than normal 10% higher yield and 75% less water use than the Checkbook Method
2014 – Evaluated at SIRP and Tifton Replicated plot studies, 4 varieties at each location July and August drier than normal Approximately same yields as the Checkbook Method with about 40% less irrigation water

Next StepsContinued testing and regular improvements
Evaluate response of producer fields
Nationalize footprint Replace weather station data with other sources
