Soil great group
Cuarzipsament
Of the Psament suborder; it It is almost pure quartz sand, without minerals that provide nutrients..
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 | Entisol | Soil without diagnostic horizons, or almost: recently deposited material (sand, alluvium) or on which the climate did not have time to act. |
|---|---|---|
| Suborder | Psament | Entisol sandy throughout the profile: dunes, sand sheets. |
| Great group | Cuarzipsament | Within the Psament suborder, it It is almost pure quartz sand, without minerals that provide nutrients.. |
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.
