Soil subgroup

Endoacualf típico

It is the central concept of the great group: it has its features and none that brings it closer to another group.

What the name says

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

Taxonomic orderAlfisolSoil with a clay accumulation horizon (argillic or natric) and good base saturation, but without the thick, dark surface of a Molisol.
SuborderAcualfAlfisol with excess water: saturated near the surface part of the year, with redox depletions.
Great groupEndoacualfWithin the Acualf suborder, it saturates from below: by a close water table.
SubgrouptípicoIt is the central concept of the great group: it has its features and none that brings it closer to another group.

What it means for farming

Acceptable fertility, but the surface layer is thinner and poor in organic matter. In the Pampas region many Alfisoles are sodic or floodable (Natracualfes) and are left for livestock.

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.
