Polycrystalline potash, with a U.S. penny for reference. (The coin is 19 mm (0.75 in) in diameter and copper in color.) Potash (/ ˈpɒtæʃ / 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 ...
Potassium is a chemical element; it has symbol K (from Neo-Latin kalium) and atomic number 19. It is a silvery white metal that is soft enough to easily cut with a knife. [8] Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure.
One of the major sources for chemical fertilizers is potash ore. [2] The other concern with the potash ore is the supply is finite and is running out, hence the increase in pricing. [1] Potash is one of the major sources for potassium and phosphorus and one of the original agrominerals. [2]
Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O. 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3−, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [5]
Because potash imparts excellent clarity to glass, it is commonly used in eyeglasses, glassware, televisions, and computer monitors. Because natural potassium contains a tiny amount of the isotope potassium-40 , potassium chloride is used as a beta radiation source to calibrate radiation monitoring equipment .
Mining of sulfur from a deposit at the edge of Ijen 's crater lake, Indonesia. Mining is the extraction. geological materials and minerals from. surface of the Earth. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory.
A farmer spreading manure to improve soil fertility. A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments.
An alum (/ ˈæləm /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl (SO. 4) 2·12 H. 2O, such that X is a monovalent cation such as potassium or ammonium. [1] By itself, "alum" often refers to potassium alum, with the formula KAl (SO. 4) 2·12 H.
