Potassium chloride is one of the essential nutrients, which is absorbed by crops in large quantities. This nutrient is indispensable for plant growth, increasing production and improving the quality of crops.
Potassium is the third major plant and crop nutrient after nitrogen and phosphorus.
In agriculture, potassium chloride (potash) improves water retention, yield, nutrient value, taste, color, texture, and disease resistance of food crops. It has wide application to fruit and vegetables, rice, wheat, and other grains, sugar, corn, soybeans, palm oil, and cotton, all of which benefit from the nutrient’s quality-enhancing properties.
In addition to its use as a fertilizer, potassium chloride is important in industrialized economies, where it is used in aluminum recycling, by the chloralkali industry to produce potassium hydroxide, in metal electroplating, as an oil-well drilling fluid, in snow and ice melting, steel heat-treating, and water softening.
The Salar de Atacama is a source of underground brines containing lithium and potassium found under the salt surface crust. Salar brines are located in the nucleus of the Salar de Atacama. From this natural resource Albemarle produces lithium carbonate, lithium chloride, potassium chloride, and magnesium chloride.
