Definition
Meaning and Definition
A white, powdery deposit of soluble salts (like sodium carbonate) left on the ground surface in arid regions due to evaporation of saline water.
Soil or land that is rendered infertile due to a high concentration of these surface salts, particularly sodium and potassium carbonates. The term can also refer to the mineral deposits themselves.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning, but more likely encountered in agricultural/geological literature from arid regions of North America (e.g., western US) than in the UK due to geography. The UK equivalent concept might be 'saline seep' or simply 'salts'.
Connotations
Connotes barren, unproductive land, and specific farming challenges. In both dialects, it's a technical descriptor.
Frequency
Much more frequent in American English, given the prevalence of the problem in the western states.
