Potassium is an essential mineral required for normal body function. It helps maintain normal blood pressure, fluid and electrolyte balance, muscle and nerve function, as well as bone density. This three-page fact sheet describes potassium and its normal dietary importance, as well as the impact potassium levels have on those with Chronic Kidney Disease. Written by Ashley R. Kendall, Nancy J. Gal, and Wendy J. Dahl and published by the Food Science and Human Nutrition Department.

Potassium (K) for Citrus Trees

Potassium moves from leaves to fruit and seeds as they develop. Potassium is necessary for several basic physiological functions such as the formation of sugars and starch, synthesis of proteins, normal cell division and growth, and neutralization of organic acids. Potassium is important in fruit formation and enhances fruit size, flavor, and color. This nutrient also helps to reduce the influence that adverse weather conditions (such as drought, cold, and flooding) have on citrus trees.
