1 In Photosynthesis, potassium regulates the opening and closing of stomata, and therefore regulates CO2 uptake. 2  Potassium triggers activation of enzymes and is essential for production of Adenosine Triphosphate (ATP). 3  ATP is an important energy source for many chemical processes taking place in plant issues. Protein and starch synthesis in plants require potassium as well. 2  Potassium is essential at almost every step of the protein synthesis. 3  In starch synthesis, the enzyme responsible for the process is activated by potassium.
Uses: Potash is in high demand as a fertilizer. Potassium, found in most soils, is an element that is essential for plant growth. An alloy of potassium and sodium is used as a heat transfer medium. Potassium salts have many commercial uses. Sources: Potassium is the 7th most abundant element on earth, making up 2.4% of the earth's crust, by weight. 1  Potassium is not found free in nature. 2  In addition to other locations, potash is mined in Germany, Utah, California, and New Mexico.
