Soil subgroup

Vitrandept típico

It is the central concept of the great group: it has its features and none that brings it closer to another group.

Vitrandept 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 Vitrand (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 orderInceptisolSoil young, with some development below the surface (a cambic horizon) but without the clay accumulation or dark surface that would define other orders.
SuborderAndeptInceptisol formed on volcanic ash.
Great groupVitrandeptWithin the Andept suborder, it It has a lot of little altered volcanic glass.
SubgrouptípicoIt 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

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.
