Soil subgroup
Hidracuent hístico
It has an organic, peat surface 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 | Acuent | Entisol with excess water: saturated near the surface, with redox depletions. |
| Great group | Hidracuent | Within the Acuent suborder, it is almost permanently saturated with water, with fluid material that does not support weight. |
| Subgroup | hístico | It has an organic, peat surface layer. |
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.
Where it is found
It does not appear on the national map; on the detailed maps it adds up to about 948 ha, across 1 districts.
Districts where it is most common
It also appears on the detailed maps of: Entre Ríos.
Other Hidracuent subgroups
Soils it shares map units with
Several soils share each map unit. These are the ones most often found alongside this one: on a property, you will likely find them in the nearby low ground or on the next rise.
The definitions are a plain-language summary of the USDA Keys to Soil Taxonomy. The formal definition includes thickness, color and percentage thresholds that are left out here.
