| 1. | It adapts well to ultisols and oxisols and can tolerate long dry periods.
|
| 2. | Ultisols occur in humid temperate or tropical regions.
|
| 3. | The oldest fossil ultisols are known from the Carboniferous period when forests first developed.
|
| 4. | In the World Reference Base for Soil Resources system, most ultisols are known as acrisols.
|
| 5. | Total potassium in the Cecil is higher than typical for Ultisols due to the presence of mica.
|
| 6. | Within its native range it will often grow on soils of Inceptisols, Ultisols, and Alfisols groups.
|
| 7. | Ultisols can have a variety of clay minerals, but in many cases the dominant mineral is kaolinite.
|
| 8. | Four soil orders are found in the upstream river basin viz . ultisols, alfisols, inceptisols and entisols.
|
| 9. | Entisols, Inceptisols, Mollisols, Spodosols, Alfisols, Ultisols, Oxisols, Aridisols, Vertisols, Andisols and Histosols.
|
| 10. | This is in contrast to Ultisols, which are the more highly leached forest soils having less than 35 % base saturation.
