| Precipitation seasonality | 8.4 – 141.52 | 9.6 – 137.44 |
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 | 9.1 – 43.99 | 10.55 – 37.45 |
| Clay | % | 11 – 47.26 | 13.6 – 43.7 |
| Coarse fragments | % | 2.21 – 36 | 3.3 – 31.2 |
| Total nitrogen | g/kg | 0.32 – 19 | 0.4 – 7.65 |
| pH | — | 4.5 – 8.6 | 4.7 – 8.1 |
| Sand | % | 15.2 – 69.91 | 21.1 – 62.75 |
| Soil organic carbon | g/kg | 5.08 – 188.47 | 7.53 – 138.65 |
These soil preferences should be compared with the site profile and the confidence of the local data.
