What the name says
Soil Taxonomy names are built from parts, and each part says something about the soil. From general to specific:
| Taxonomic order | Inceptisol | Soil young, with some development below the surface (a cambic horizon) but without the clay accumulation or dark surface that would define other orders. |
|---|---|---|
| Suborder | Acuept | Inceptisol with excess water and redox depletions near the surface. |
| Great group | Fragiacuept | Within the Acuept suborder, it has a fragipan: a dense, brittle layer that stops roots and water. |
What it means for farming
Intermediate aptitude and very dependent on location. In Argentina there are many Acueptes: Inceptisoles with excess water, often saline or sodic.
