1 IrriSatSMS Satellite and SMS Irrigation Scheduling Service John Hornbuckle, Nick Car & Evan Christen

2 IrriSatSMS - Satellite and SMS Irrigation Scheduling Service Aims to overcome the costs and complexities of irrigation scheduling Capturing the bulk of the ‘market’ and providing them with a tool for assisting these decisions can deliver real water savings The system provides irrigation scheduling information specific for a farm at an extremely low cost, directly to their mobile phone, taking into account the latest weather conditions and their crop needs ensuring decisions on irrigation are made with the best available information

3 How does IrriSatSMS schedule ? Using the FAO 56 approach ETc = ETo x Kc Actual water use of crop Reference water use – weather station Crop Coefficient – relates your crop to the reference crop

4 Gaining individual crop coefficients Multi-spectral (Spot,Landsat, Iknonos) satellites cover MIA approx. every 7-14 days Images of everyone's individual crop Can this information can be used for gaining the crop coefficient

5 USDA – Trout, Ayars

6 Determining Kc from NDVI - grapevines Kc = 2.26 x NDVI – 0.4352

7 How does the IrriSatSMS schedule ? Using the FAO 56 approach ETc = ETo x Kc Actual water use of crop.. But still in a format that’s not much use!

8 Making the scheduling information useful Irrigation Rainfall

9 Overview of IrriSatSMS Determination of a crop coefficient (Kc) from satellite image ETo from Weather Station or SILO Incorporates management/soil/water/salinity constraints On Ground Satellite images used to determine plant performance of an irrigators crop Representing Individual Paddocks Satellite Measurements Potential Evaporation based on Atmospheric Demand ETc = ETo X Kc Crop water use determined and irrigation requirement Daily irrigation scheduling information delivered to irrigators through SMS

10 Benchmarking and auditing

11 Try a Demonstration Now! SMS demo run times to 0416 905 013 and you’ll receive a demonstration SMS reply for grapevines in Griffith, NSW

12 Future efforts/issues

13 Understanding and irrigating for spatial variability – making use of RS data

14 Rastus – spatial soil, water, plant model

15 Future efforts/issues RS for assessing crop/plant stress i.e. LWP from RS – implementing RDI, SDI irrigation strategies for monitoring water stress for improved quality – a simple thermal type approach Soil moisture – deeper and with greater resolution Linking RS data with irrigation management models Large group of irrigators which we have real time water use and soil moisture monitoring (60+) senteks/cprobes Heavily instrumented field sites EB, SM, EM, ET, T, etc Very interested in being a part of any future campaign Future Campaigns
