Most of the production of potassium is used for fertilisers: Method And Arrangement For Compressing And Lumping Salts, Preferably Potassium-Fertilizer Salts (1970).

    Many potassium salts are very important:

    Potassium carbonate is used in the manufacture of Glass: Improvements In Or Relating To The Manufacture Of Resistant Glass (1923).

    Potassium hydroxide is used to make detergent and liquid soap: Process For Producing Potassium Hydroxide Of High Purity (1944).

    Potassium chloride is used in pharmaceuticals and saline drips: Method of treating hypokalemia (1991).

    Potassium reacts with water even more violently than sodium does. It’s a real blast, but don’t try this at home: https://www.youtube.com/watch?v=Jy1DC6Euqj4.
