Soil great group

Eutroboralf

Of the Boralf suborder; it has high base saturation: it is not acidic.

Eutroboralf 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 Haplocrialf.

What the name says

Soil Taxonomy names are built from parts, and each part says something about the soil. From general to specific:

Taxonomic orderAlfisolSoil with a clay accumulation horizon (argillic or natric) and good base saturation, but without the thick, dark surface of a Molisol.
SuborderBoralfAlfisol cold climate.
Great groupEutroboralfWithin the Boralf suborder, it has high base saturation: it is not acidic.

What it means for farming

Acceptable fertility, but the surface layer is thinner and poor in organic matter. In the Pampas region many Alfisoles are sodic or floodable (Natracualfes) and are left for livestock.
