Soil subgroup
Cambortid típico
It is the central concept of the great group: it has its features and none that brings it closer to another group.
Cambortid 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 Haplocambid.
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 | Aridisol | Soil arid climate: water is lacking most of the year and the profile accumulates what the rain cannot wash away (carbonates, gypsum, salts) or clay from more humid times. |
|---|---|---|
| Suborder | Ortid | Aridisol without clay horizon. |
| Great group | Cambortid | Within the Ortid suborder, it has only one cambic horizon: incipient development, no accumulations. |
| 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
Without irrigation there is no agriculture: they are soils of native woodland, extensive grazing or, with water, irrigated oases (Mendoza, San Juan, the valleys of the NOA).

How productive it is
Where it is the main soil of the map unit, the productivity index has a median of 51 (average); half of the units fall between 51 and 51.
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.
Other Cambortid 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.
