Soil great group
Psamacuent
Of the Acuent suborder; it it's sandy.
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 | Entisol | Soil without diagnostic horizons, or almost: recently deposited material (sand, alluvium) or on which the climate did not have time to act. |
|---|---|---|
| Suborder | Acuent | Entisol with excess water: saturated near the surface, with redox depletions. |
| Great group | Psamacuent | Within the Acuent suborder, it it's sandy. |
What it means for farming
Very variable. The sandy ones (Psamentes) retain little water and blow away; alluvial ones (Fluventes) can be good but they flood; the shallow ones on rock (lithic) are barely useful for grazing.
