Soil subgroup

Udifluvent óxico

It has low activity clay, with little capacity to retain nutrients: it is close to Oxisoles.

What the name says

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

Taxonomic orderEntisolSoil without diagnostic horizons, or almost: recently deposited material (sand, alluvium) or on which the climate did not have time to act.
SuborderFluventEntisol formed by layers of alluvium left by a river when it overflows; organic matter rises and falls with each layer.
Great groupUdifluventWithin the Fluvent suborder, it It is a humid climate (udic moisture regime).
SubgroupóxicoIt has low activity clay, with little capacity to retain nutrients: it is close to Oxisoles.

What it means for farming

Very variable. The sandy ones (Psamentes) retain little water and blow away; alluvial ones (Fluventes) can be good but they flood; the shallow ones on rock (lithic) are barely useful for grazing.

Where it is found

It does not appear on the national map; on the detailed maps it adds up to about 73.268 ha, across 6 districts.

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 13 (very low); half of the units fall between 13 and 13.

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.

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.

The definitions are a plain-language summary of the USDA Keys to Soil Taxonomy. The formal definition includes thickness, color and percentage thresholds that are left out here.
