Soil subgroup
Criandept lítico
It has continuous rock (lithic contact) within 50 cm: it is a shallow soil.
Criandept is a name from the 1975 taxonomy, which many INTA soil survey maps were made with. The current edition no longer has this group: today it would be classified as Criand (Andisol).
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 | Inceptisol | Soil young, with some development below the surface (a cambic horizon) but without the clay accumulation or dark surface that would define other orders. |
|---|---|---|
| Suborder | Andept | Inceptisol formed on volcanic ash. |
| Great group | Criandept | Within the Andept suborder, it It's cold weather. |
| Subgroup | lítico | It has continuous rock (lithic contact) within 50 cm: it is a shallow soil. |
What it means for farming
Intermediate aptitude and very dependent on location. In Argentina there are many Acueptes: Inceptisoles with excess water, often saline or sodic.

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.
