9. © 2009 by Adcon Telemetry GmbH » » Soil Moisture – Adjusting Run Times - Overlay irrigation data - Adjust run time to get irrigation to the desired depth - Avoid pushing water and nutrients past the root zone under irrigation over irrigation

10. © 2009 by Adcon Telemetry GmbH » » Soil Moisture - Scheduling - Add all sensor values to create “summed” or average curve - Curve represents whole profile - Full point when moisture is pushed past root zone - Refill Point when plant can not extract more - Schedule irrigation when curve approaches Refill point Refill point Full point

11. © 2009 by Adcon Telemetry GmbH » » Reference Evapotranspiration - Principles - Weather data is used to estimate crop water use - Crop coefficients are used to adjust crop water use for crop type and growth stage - Growers use a “replacement” strategy and irrigate with the quantity of water used by the plant - Adcon allows for site specific ETo

12. © 2009 by Adcon Telemetry GmbH » » Irrigation System Monitoring - Most irrigation systems are checked for uniformity of distribution - This tests only a single point in time - They do not detect changes effected by: Environmental conditions Changing well depths Clogged filters Equipment failure Human errors
