Potassium is a macronutrient that is essential for plant growth and development. It plays a critical role in many physiological processes, including photosynthesis, water regulation, and nutrient uptake. Potassium is also important for fruit quality because it helps to regulate the osmotic potential of the fruit cells, which can affect the texture, flavor, and color of the fruit.
