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]
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.

Nutrients in the soil are taken up by the plant through its roots, and in particular its root hairs.To be taken up by a plant, a nutrient element must be located near the root surface; however, the supply of nutrients in contact with the root is rapidly depleted within a distance of ca. 2 mm. [14] There are three basic mechanisms whereby nutrient ions dissolved in the soil solution are brought ...
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 ...
Potassium deficiency, also known as potash deficiency, is a plant disorder that is most common on light, sandy soils, because potassium ions (K +) are highly soluble and will easily leach from soils without colloids. [1] Potassium deficiency is also common in chalky or peaty soils with a low clay content.
[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]
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.
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]
