Potassium fertilizers: Potash is a mixture of potassium minerals used to make potassium (chemical symbol: K) fertilizers. Potash is soluble in water, so the main effort in producing this nutrient from the ore involves some purification steps; e.g., to remove sodium chloride (NaCl) (common salt). Some examples of these fertilizers are potassium chloride, potassium sulfate, potassium carbonate, or potassium nitrate.
