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 | Ultisol | Soil very washed out by a warm and humid climate, with a clay accumulation horizon and low base saturation: acidic and poor in calcium and magnesium. |
|---|---|---|
| Suborder | Udult | Ultisol humid climate, well drained. |
| Great group | Kandiudult | Within the Udult suborder, it has a kandic horizon: accumulation of low activity clay, typical of soils very washed tropical. |
| Subgroup | ródico | It has a dark red subsoil. |
