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 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.
SuborderXerertVertisol Mediterranean climate.
Great groupPeloxerertWithin 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.
