With the aim of being self-sufficient in supplies of potassium chloride (KCl), raw material for the production of potassium nitrate, SQM began operations in the Atacama Salt Flats. The initial investment included the construction of a plant for potassium chloride and potassium sulfate. Currently the business line of potassium includes the sale of these two potassium fertilizers.The main sources of potassium that exist in the market for use in fertilizers are: Potassium chloride (KCl), potassium sulfate (K2SO4) and potassium nitrate (KNO3). Of these three, potassium chloride is the most commonly used worldwide. SQM is a low-cost producer with the flexibility to produce these three sources of potassium based on market needs.

The main sources of potassium that exist on the market for use in fertilizers are: potassium chloride KCI, potassium sulfate K2SO4 and potassium nitrate KNO3. Of these sources, potassium chloride is undoubtedly the most important worldwide and SQM is the only company that produces all three sources of potassium.

Potassium deficiency in plants can cause abnormalities and affect the absorption of CO2. Additionally, potassium plays an important role in the regulation of water in plants, both in its absorption through roots and in its loss, improving resistance. of plants to water stress.
