Soil great group

Psament

Entisol sandy throughout the profile: dunes, sand sheets.

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.
SuborderPsamentEntisol sandy throughout the profile: dunes, sand sheets.

The map only classifies it down to suborder, without saying which great group it belongs to.

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 3 (very low); half of the units fall between 3 and 3.

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.

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.
