Soil subgroup
Xerortent típico
It is the central concept of the great group: it has its features and none that brings it closer to another group.
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 | Ortent | Entisol on material that is neither sandy nor alluvial: eroded slopes, rock, recent sediments. |
| Great group | Xerortent | Within the Ortent suborder, it It has a Mediterranean climate (xeric moisture regime). |
| Subgroup | típico | It is the central concept of the great group: it has its features and none that brings it closer to another group. |
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.

How productive it is
Where it is the main soil of the map unit, the productivity index has a median of 65 (Well); half of the units fall between 50 and 80.
Taken from the maps that include this data. A map unit with several soils has a single index, and it is only attributed to the dominant soil.
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.
