| Precipitation seasonality | 27.28 – 120.44 | 41.44 – 119.12 |
These values describe the documented climate envelope of the taxon. They are not, by themselves, a local recommendation.
Documented soil preferences
| Variable | Unit | Observed range | Central range |
|---|---|---|---|
| Cation exchange capacity (CEC) | cmol(+)/kg | 11 – 13.9 | 11.6 – 13.1 |
| Clay | % | 15 – 17.9 | 15 – 17.1 |
| Coarse fragments | % | 10.6 – 17.9 | 11.12 – 16.9 |
| Total nitrogen | g/kg | 0.48 – 0.57 | 0.5 – 0.55 |
| pH | — | 7.5 – 9 | 8.1 – 8.9 |
| Sand | % | 58 – 72.5 | 58.1 – 72.5 |
| Soil organic carbon | g/kg | 3.2 – 4.1 | 3.2 – 4 |
These soil preferences should be compared with the site profile and the confidence of the local data.
