Soil great group
Peloxerert
Of the Xerert suborder; it has dark, low chroma colors at the top.
Peloxerert 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 Haploxerert.
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 | Xerert | Vertisol Mediterranean climate. |
| Great group | Peloxerert | Within the Xerert 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.
