Soil subgroup

Halacuept aérico

Being a soil with excess water, the upper part is better aerated than in the typical one: fewer gray colors.

What the name says

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

Taxonomic orderInceptisolSoil young, with some development below the surface (a cambic horizon) but without the clay accumulation or dark surface that would define other orders.
SuborderAcueptInceptisol with excess water and redox depletions near the surface.
Great groupHalacueptWithin the Acuept suborder, it is it saline or sodic.
SubgroupaéricoBeing a soil with excess water, the upper part is better aerated than in the typical one: fewer gray colors.

What it means for farming

Intermediate aptitude and very dependent on location. In Argentina there are many Acueptes: Inceptisoles with excess water, often saline or sodic.

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.
