Soil great group
Fluvent
Entisol formed by layers of alluvium left by a river when it overflows; organic matter rises and falls with each layer.
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 | Fluvent | Entisol formed by layers of alluvium left by a river when it overflows; organic matter rises and falls with each layer. |
The map only classifies it down to suborder, without saying which great group it belongs to.
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.
