  2. Potassium in biology - Wikipedia

    en.wikipedia.org/wiki/Potassium_in_biology

    A deficiency of potassium ions can impair a plant's ability to maintain these processes. Potassium also functions in other physiological processes such as photosynthesis, protein synthesis, activation of some enzymes, phloem solute transport of photoassimilates into source organs, and maintenance of cation:anion balance in the cytosol and vacuole.

  3. Potassium cycle - Wikipedia

    en.wikipedia.org/wiki/Potassium_cycle

    The most abundant ion in plant cells is the potassium ion. [2] Plants take up potassium for plant growth and function. A portion of potassium uptake in plants can be attributed to weathering of primary minerals, but plants can also ‘pump’ potassium from deeper soil layers to increase levels of surface K. [2] Potassium stored in plant matter can be returned to the soil during decomposition ...

  4. Mineral absorption - Wikipedia

    en.wikipedia.org/wiki/Mineral_absorption

    In plants and animals, mineral absorption, also called mineral uptake is the way in which minerals enter the cellular material, typically following the same pathway as water. In plants, the entrance portal for mineral uptake is usually through the roots. Some mineral ions diffuse in-between the cells. In contrast to water, some minerals are ...

  5. Plant nutrition - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrition

    The potassium ion (K +) is highly mobile and can aid in balancing the anion (negative) charges within the plant. A relationship between potassium nutrition and cold resistance has been found in several tree species, including two species of spruce. [12] Potassium helps in fruit coloration, shape and also increases its brix. Hence, quality ...

  6. Plant nutrients in soil - Wikipedia

    en.wikipedia.org/wiki/Plant_nutrients_in_soil

    The amount of potassium in a soil may be as much as 80,000 lb per acre-foot, of which only 150 lb is available for plant growth. Common mineral sources of potassium are the mica biotite and potassium feldspar, KAlSi 3 O 8. Rhizosphere bacteria, also called rhizobacteria, contribute through the production of organic acids to its solubilization. [87]

  7. Potassium deficiency (plants) - Wikipedia

    en.wikipedia.org/wiki/Potassium_deficiency_(plants)

    A deficiency of potassium ions can impair a plant's ability to maintain these processes. Potassium also functions in other physiological processes such as photosynthesis, protein synthesis, activation of some enzymes, phloem solute transport of photoassimilates into source organs, and maintenance of cation:anion balance in the cytosol and vacuole.

    Needed for production of hydrochloric acid in the stomach, in cellular pump functions and required in host defense Table salt (sodium chloride) is the main dietary source. hypochloremia / hyperchloremia: Sodium: 1500 2300; NE: A systemic electrolyte and is essential in coregulating ATP with potassium

  9. Potassium - Wikipedia

    en.wikipedia.org/wiki/Potassium

    Potassium is formed in supernovae by nucleosynthesis from lighter atoms. Potassium is principally created in Type II supernovae via an explosive oxygen-burning process. [51] These are nuclear fusion reactions, not to be confused with chemical burning of potassium in oxygen. 40 K is also formed in s-process nucleosynthesis and the neon burning ...
