Soil great group

Epiacuent

Of the Acuent suborder; it saturated from above: rainwater hangs on a poorly permeable layer.

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 groupEpiacuentWithin the Acuent suborder, it saturated from above: rainwater hangs on a poorly permeable layer.

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.
