Pistachio
ExperimentalThe sensor gives usable readings here, but the dataset is thin and there are no published thresholds. Sold for research and supervised field trials only — not for commercial irrigation scheduling. Growers: stick to the Validated list.
Performance
Recommended for experimental use. Field trials show good agreement between the sensor and pressure chamber. Sensors sometimes randomly get flooded and proceed to measure zero SWP. Reinstalling the sensor will usually fix this. We are testing to better understand what causes this wounding response and how to prevent it.
Known Issues
- Pistachio trees produce latex, which can (randomly) interfere with sensor measurement. Sensors should be reinstalled if they get stuck at zero SWP.
