What the name says

Soil Taxonomy names are built from parts, and each part says something about the soil. From general to specific:

Taxonomic orderEntisolSoil without diagnostic horizons, or almost: recently deposited material (sand, alluvium) or on which the climate did not have time to act.
SuborderOrtentEntisol on material that is neither sandy nor alluvial: eroded slopes, rock, recent sediments.
Great groupXerortentWithin the Ortent suborder, it It has a Mediterranean climate (xeric moisture regime).

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.
