Yara Water Solution Remote measurement of plant water status in real time via Internet • Plant based, continuous and non-destructive measurement of plant water status • Online data transmission and web-based access via My. Yara • Automatic, validated crop specific irrigation recommendation

The measuring principle of the Yara Water-Sensor high turgor = high water status low turgor = low water status Turgor pressure is the driving force for plant growth and fruit production.

The measuring principle of the Yara Water-Sensor threaded rod magnetic pressure movable toric magnet leaf turgor pressure sensor lower toric magnetic pressure cable to Transmitter The Yara Water-Sensor measures the difference between magnetic pressure and turgor pressure.

The measuring principle of the Yara Water-Sensor s s o l r te a w water Signal of a Yara Water. Sensor (k. Pa) low water status medium water status high water status Water status Turgor pressure is lost during the day due to water loss by transpiration and recovered during the night. If there is no water available the plants cannot recover their turgidity and the water status decreases. The Yara Water-Sensor detects these changes.

Integrating Yara Water Solution and My. Yara Irrigation Plot 10 x Yara Water. Sensor 1 x Temperature-, 1 x Humidity- and 1 x Soil Moisture. Sensor 5 x Transmitter Radio transmission with 1. 500 m range 1 x Base Station GSM transmission to My. Yara Decrease irrigation Consider reduction in irrigation No change recommended, irrigation within the strategy Consider increase in irrigation Increase irrigation The Yara Water-Sensor data together with the microclimate data are sent wireless to the My. Yara server. The signals are evaluated and the irrigation recommendation can be accessed online.

Value proposition elements By implementing the Yara Water Solution it is possible to… 1. save water 2. save energy 3. reduce tree maintenance 4. sustain maximum yield 5. water plants on demand 7

Use Cases | Calibrated Crops The Yara Water-Sensor is calibrated for olives and citrus, however extensive work is ongoing for additional crops – such as apples, cherries, almonds and grapes.
