Soil subgroup
Hapludert éntico
It has minimal development: under the dark surface there is no marked B horizon. It is usually sandier and retains less water than the typical one.
What the name says
Soil Taxonomy names are built from parts, and each part says something about the soil. From general to specific:
| Taxonomic order | Vertisol | Soil 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. |
|---|---|---|
| Suborder | Udert | Vertisol humid climate: cracks open for a short time each year. |
| Great group | Hapludert | Within the Udert suborder, it It is the simplest of the suborder: it does not have a clay horizon or any other feature that places it in a more specific group.. |
| Subgroup | éntico | It has minimal development: under the dark surface there is no marked B horizon. It is usually sandier and retains less water than the typical one. |
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.

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.
