A technical term in pedology (soil science) for Mollisols or Chernozems formed under tallgrass prairie vegetation; also used metaphorically to refer to agricultural land or the fertility of the American Midwest.
Dialectal Variation
British vs American Usage
Differences
The term is predominantly used in an American context due to the association with North American prairies. In British English, it is rarely encountered outside specialised academic texts. British soil science might use more generic terms like 'deep grassland soil' or the international classification 'Chernozem' or 'Mollisol'.
Connotations
In American English, it connotes fertility, agricultural heartland, and the history of westward expansion. In British English, it is a neutral, foreign technical term.
Frequency
Extremely low frequency in general British English; low to medium frequency in American academic/geographical contexts.
