Soil subgroup

Peludert mólico

It has a dark surface rich in organic matter, almost like that of a Molisol.

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 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.
SuborderUdertVertisol humid climate: cracks open for a short time each year.
Great groupPeludertWithin the Udert suborder, it has dark, low chroma colors at the top.
SubgroupmólicoIt has a dark surface rich in organic matter, almost like that of a Molisol.

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.

Where it is found

It does not appear on the national map; on the detailed maps it adds up to about 87.396 ha, across 5 districts.

Districts where it is most common

It also appears on the detailed maps of: Entre Ríos.

How productive it is

Where it is the main soil of the map unit, the productivity index has a median of 25 (low); half of the units fall between 25 and 25.

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.

Soil series

Series are the specific soils, named after places, that detailed maps describe under this name. Two properties with the same series have the same 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.
