Potassium chloride (KCl) is a crystalline salt commonly used as a potassium fertilizer in agriculture and also finds applications in various industrial processes. It is a white or colorless solid with a salty taste and is highly soluble in water. Potassium chloride occurs naturally as sylvite and carnallite minerals or is produced synthetically through chemical processes. It plays a vital role in plant nutrition by providing essential potassium, which is necessary for enzyme activation, osmoregulation, and overall plant growth.
