Soil subgroup

Psamacuent espódico

It has features of spodic horizon: accumulation of humus, aluminum and iron.

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 groupPsamacuentWithin the Acuent suborder, it it's sandy.
SubgroupespódicoIt has features of spodic horizon: accumulation of humus, aluminum and iron.

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.

How productive it is

Where it is the main soil of the map unit, the productivity index has a median of 24 (low); half of the units fall between 23 and 24.

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 Psamacuent 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.
