What do we know?• Timing

• Temperature

• Provides objective information for decision making

Precision Irrigation• Two big questions

o When?o How much?

• Measure water potential

• Measure soil moisture

• Benefitso Apply the amount of water needed…no more…no less ($ saved)o 5 – 10% Increase in production ($ earned)
