  2. 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 ...

  3. Solvay process - Wikipedia

    en.wikipedia.org/wiki/Solvay_process

    The Solvay process or ammonia–soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia–soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. [1]

  4. Potash - Wikipedia

    en.wikipedia.org/wiki/Potash

    Potash (/ ˈ p ɒ t æ ʃ / POT-ash) includes various mined and manufactured salts that contain potassium in water-soluble form. [1] The name derives from pot ash, plant ashes or wood ash soaked in water in a pot, the primary means of manufacturing potash before the Industrial Era. The word potassium is derived from potash. [2]

  5. Soil formation - Wikipedia

    en.wikipedia.org/wiki/Soil_formation

    Soil develops through a series of changes. [2] The starting point is weathering of freshly accumulated parent material.A variety of soil microbes (bacteria, archaea, fungi) feed on simple compounds released by weathering and produce organic acids and specialized proteins which contribute in turn to mineral weathering.

    These activities include loosening the soil, seeding, special watering, moving plants when they grow bigger, and harvesting, among others. Without these activities, a crop cannot be grown. The main steps for agricultural practices include preparation of soil, sowing, adding manure and fertilizers, irrigation, harvesting and storage.

  7. Seaweed fertiliser - Wikipedia

    en.wikipedia.org/wiki/Seaweed_fertiliser

    [22] [18] The industry developed out of demand for ashed soda, or potash, which was used to create glass and soap, and led to shortages for agricultural applications in traditional coastal communities. Potash is a water-soluble potassium rich concentrate made from plant matter, so it was also exported as a fertilizer. [18]

  8. Ashery - Wikipedia

    en.wikipedia.org/wiki/Ashery

    The potash could then be baked in a kiln to further refine the substance into a pearly white material called pearl ash, pearl-ash or pearlash. The lye and potash stages were commonly performed on site by the settlers themselves, and the asheries only performed the final step and most difficult step of converting the black salts to pearlash .

  9. Potassium silicate - Wikipedia

    en.wikipedia.org/wiki/Potassium_silicate

    Impregnation of wood with a potassium silicate solution is an easy and low-cost way for rendering the woodwork of houses secure against catching fire. The woodwork is first saturated with a diluted and nearly neutral solution of potash silicate. After drying, one or two coats of a more concentrated solution are usually applied. [2]
