Soil subgroup

Epiacuert 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 orderVertisolSoil very clayey, with clays that swell when wet and contract when dry: when dry it opens wide and deep cracks, and when wet the layers slide against each other leaving slickensides.
SuborderAcuertVertisol with excess water and redox depletions near the surface.
Great groupEpiacuertWithin the Acuert suborder, it saturated from above: rainwater hangs on a poorly permeable layer.
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

Fertile and with a lot of water retained, but difficult: they become waterlogged, when wet they become sticky and difficult to work with, and when dry they crack. They ask for tillage at the right time. They are the typical soil of much of Entre Ríos.

class V: 100%

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.

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.
