Soil great group
Peludert
Of the Udert suborder; it has dark, low chroma colors at the top.
Peludert is a name from the 1975 taxonomy, which many INTA soil survey maps were made with. The current edition no longer has this group: today it would be classified as Hapludert.
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 | Peludert | Within the Udert suborder, it has dark, low chroma colors at the top. |
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.
It is the Vertisol of Entre Ríos in the old soil survey maps: the current classification changes it to Hapludert.

How productive it is
Where it is the main soil of the map unit, the productivity index has a median of 27 (low); half of the units fall between 22 and 29.
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.
