ultisol
LowTechnical/Academic
Definition
Meaning
A highly weathered soil type with subsurface clay accumulation, typically found in humid tropical and subtropical regions.
Ultisols are one of the twelve soil orders in USDA soil taxonomy, characterized by low base saturation and often requiring lime for agricultural use due to intense weathering under high rainfall and temperature conditions.

Common Pitfalls
Translation Traps (for Russian speakers)
- Might be directly translated as 'ультисоль', but it's a technical loanword; ensure correct context in soil science.
- Avoid confusing with 'ультра' meaning 'ultra', as the term specifically refers to a soil classification.
Common Mistakes
- Mispronouncing with stress on the second syllable, e.g., 'ul-TI-sol'.
- Using it interchangeably with 'oxisol' or other soil orders without proper distinction.

Frequently Asked Questions
Ultisol is a soil order characterized by high weathering and clay accumulation in the subsurface, typically in humid regions.
They are commonly found in humid tropical and subtropical regions, such as parts of Southeast Asia and the southeastern United States.
Due to low fertility and acidity, ultisols often require soil amendments like lime and fertilizers for effective agricultural use.
No, it is a technical term primarily used in soil science and related academic or technical fields, not in everyday language.
