Definition
Meaning
A white, gray, or colorless mineral consisting of hydrated magnesium sulfate (MgSO₄·H₂O).
A naturally occurring mineral used in agriculture as a magnesium fertilizer and in some industrial processes.
Linguistics
Semantic Notes
Primarily used in mineralogy, geology, and agricultural chemistry. Its meaning is highly specific and context-bound.

Usage
Context Usage
Business
Only in niche sectors like fertilizer production or mineral trading: 'The company secured a new contract for kieserite supply.'
Academic
In geology and agricultural science papers: 'The evaporite sequence is dominated by halite and kieserite.'
Everyday
Virtually never used in everyday conversation.
Technical
The primary context: 'Kieserite's low solubility makes it a slow-release magnesium source for crops.'
Examples
By Part of Speech
adjective
British English
- The kieserite layers were clearly visible.
- A kieserite-bearing rock sample was analysed.
American English
- The kieserite layers were clearly visible.
- A kieserite-bearing rock sample was analyzed.
Examples
By CEFR Level
- Kieserite is a mineral.
- It is used in some fertilizers.
- Farmers sometimes use kieserite to add magnesium to deficient soils.
- The geologist identified kieserite among the other evaporite minerals.
- Unlike the more soluble epsomite, kieserite's monohydrate structure renders it a slow-release magnesium supplement ideal for certain soil conditions.
- X-ray diffraction confirmed the presence of sylvite, carnallite, and kieserite in the drill core sample.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid confusing it with более общих терминов like 'сульфат' (sulfate) or 'магний' (magnesium). 'Kieserite' is the specific mineral form.
- The word is a direct loan (киезирит/kiezerit), so it should be recognized but its precise technical meaning may be unfamiliar.
Common Mistakes
- Mispronouncing it as /ˈkaɪzəraɪt/.
- Using it in non-technical contexts where 'Epsom salts' (magnesium sulfate heptahydrate) or simply 'magnesium sulfate' would be more appropriate.
- Misspelling as 'keiserite' or 'kieserit'.

FAQ
Frequently Asked Questions
No. Both contain magnesium sulfate, but Epsom salt is the heptahydrate form (MgSO₄·7H₂O), which is highly soluble. Kieserite is the monohydrate (MgSO₄·H₂O) and is less soluble, acting as a slow-release fertilizer.
It is typically found in marine evaporite deposits, often associated with salt beds, potash minerals, and other sulfates like anhydrite. Major deposits exist in Germany, the United States, and Russia.
It is named after the German chemist and apothecary Dietrich Georg von Kieser (1779–1862).
It would be highly unusual and overly technical. In general gardening contexts, terms like 'magnesium fertilizer' or specific product names are used instead.
