Ash
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 early experimental use. Researchers tested sensors in Ash with reasonable results, but had issues with the sensor installation depth. In ring-porous species, the sensor must be installed in the outtermost xylem for best results.
Installation Tips
- Likely will need to use thick-bark installation method.
- Use of the new 7mm probe strongly recommended. This probe has consistently shallow installation depth, as required by this specie.
References
- In ring-porous and thick-barked species, improper installation depth was a major source of error in ystem measurements, resulting in little to no variability of readings. The problem occurred most frequently for microtensiometers in ash trees, due to small sapwood depth, and required reinstallation to ensure correct placement.
