Soil subgroup
Borohemist lítico
It has continuous rock (lithic contact) within 50 cm: it is a shallow soil.
Borohemist 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 Cryohemist.
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 | Histosol | Soil organic: peat or plant material accumulated where water does not allow it to decompose. More than half of the top profile is organic matter. |
|---|---|---|
| Suborder | Hemist | Histosol of moderately decomposed plant material. |
| Great group | Borohemist | Within the Hemist 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
Peatlands and wet meadows. They have no agricultural use; they have value as a reserve of water and carbon.

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.
