Soil subgroup

Udipsament ácuico

Shows signs of saturation with water within the first meter (mottles, gray reduction colors): it has a temporary water table or waterlogging.

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.
Great groupUdipsamentWithin the Psament suborder, it It is a humid climate (udic moisture regime).
SubgroupácuicoShows signs of saturation with water within the first meter (mottles, gray reduction colors): it has a temporary water table or waterlogging.

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.
