1 SmartIrrigation Apps K.W. Migliaccio, G. Vellidis, C. Fraisse, K.T. Morgan, J. Andreis, D. Rowland, L. Zotarelli Water Institute Symposium Feb

2 Goals Dynamic thinking Professional products Build on strengths expertise Become a source of apps for southeast not just irrigation Long term sustainability 2

3 Motivating factors: irrigation apps Need Irrigation is a large user of groundwater and surface water (60% worldwide of fresh water USGS) Demand for fresh water resources expected to increase Knowledge and information Commodity specific irrigation research Availability of weather data Drought adaptation strategies Climate change and variability Implementation opportunity Computing power dynamic possibilities Availability and widespread use of technology 3

4 App purpose: irrigation scheduling Provide the most accurate, site-specific, realtime and forecast information Minimum user input Ready to use output provided Notify user as needed, no requirements of user to consistently remember to check Engaging, not static 4

5 Basis of irrigation schedule Weather data from FAWN and GAEMN Citrus, strawberry, and urban turf Uses average FAO PM ET with Kc from previous 5 days, updates every 15 days If schedule changes more than 50%, updates are sent prior to 15 days Citrus, Strawberry, Urban turf, and Cotton apps 5

6 Citrus app Irrigation system: micro sprinkler Tree row distances, emitter characteristics, soil type, irrigation depth, trigger depth Irrigation delays for rainfall amounts (days) Irrigation schedule (minutes) every so many days User can select the day of week to receive irrigation notifications 6

7 Citrus screenshot Dr. Kelly Morgan (Immokalee) App store: Smartirrigation citrus 7

8 Strawberry app Irrigation system: drip Between-row, planting date, harvest date, irrigation rate, efficiency Irrigation schedule (minutes/hrs) and degree days accumulated for everyday irrigation Drs. Kelly Morgan or Clyde Fraisse App store: Smartirrigation citrus, Smartirrigation strawberry 8

9 Urban turf app Irrigation system: sprinkler heads Soil type, root depth Micro sprinkler, spray, multi-stream spray, gear driven rotors, impacts Days of week to irrigate Irrigation schedule in minutes considering number of irrigation events per week Notifications used to adjust irrigation schedules due to rainfall 9

10 Dr. Kati Migliaccio App store: Smartirrigation turf EDIS available AE499 10

11 mm/day Evaluation of previous 5 day approach Alachua ETo 5-day mean Aug-12 Sep-12 Nov-12 Jan-13 Feb-13 Apr-13 Jun-13 Jul-13 Sep-13 Nov-13 Currently using last 5 days new resources may become available to use predicted ET 11

12 Cotton app Irrigation application rate Plant phenology and crop coefficient (Kc) change with accumulated heat units (GDDs) User can override GDD-driven phenology Does not recommend irrigation amounts Advises user of available soil water and stress threshold 12

13 Cotton app Uses real-time rain data from FAWN and GAEMN A daily water balance approach: allow for R to be changed and I to be input Contact Dr. George Vellidis (UGA) 13

14 Forecast data National Weather Service data: temperature, relative humidity, wind speed, probability of rain Current conditions Forecast by hour for next 11 hrs Forecast by day for next 5 days 14

15 Cumulative Irrigation (in) Cumulative irrigation by treatment Control ET RB ET Htr App /2/13 11/12/13 11/22/13 12/2/13 12/12/13 12/22/13 1/1/14 1/11/14 1/21/14 1/31/14 2/10/14 15

16 Component to be modified or added Drought adaptation Irrigate to field capacity or percentage of field capacity Early stress of plants Rainfall data Testing different sources of data Greater spatial variability and accuracy Water savings Provide users with an assessment of their savings using the app 16

17 Additional apps Peanut (Diane Rowland) Avocado (Kati Migliaccio and Jonathan Crane) Cabbage (Lincoln Zotarelli) Tomato (Kelly Morgan) 17
