Soil subgroup

Hidracuent típico

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

What the name says

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

Taxonomic orderEntisolSoil without diagnostic horizons, or almost: recently deposited material (sand, alluvium) or on which the climate did not have time to act.
SuborderAcuentEntisol with excess water: saturated near the surface, with redox depletions.
Great groupHidracuentWithin the Acuent suborder, it is almost permanently saturated with water, with fluid material that does not support weight.
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

Very variable. The sandy ones (Psamentes) retain little water and blow away; alluvial ones (Fluventes) can be good but they flood; the shallow ones on rock (lithic) are barely useful for grazing.

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.
