Soil subgroup

Borofibrist lítico

It has continuous rock (lithic contact) within 50 cm: it is a shallow soil.

Borofibrist 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 Cryofibrist.

What the name says

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

Taxonomic orderHistosolSoil organic: peat or plant material accumulated where water does not allow it to decompose. More than half of the top profile is organic matter.
SuborderFibristHistosol of slightly decomposed plant material: the fibers are recognized.
Great groupBorofibristWithin the Fibrist suborder, it It's cold weather.
SubgrouplíticoIt has continuous rock (lithic contact) within 50 cm: it is a shallow 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.
