Phosphate rich organic manure is a type of fertilizer used as an alternative to diammonium phosphate and single super phosphate.. Phosphorus is required by all plants but is limited in soil, creating a problem in agriculture In many areas phosphorus must be added to soil for the extensive plant growth that is desired for crop production.
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.
Potassium sulfate (US) or potassium sulphate (UK), also called sulphate of potash (SOP), arcanite, or archaically potash of sulfur, is the inorganic compound with formula K 2 SO 4, a white water-soluble solid. It is commonly used in fertilizers, providing both potassium and sulfur.
Therefore, pure KCl is 39.09/(39.09 + 35.45) = 52% potassium and 48% chlorine by weight. Its K value is therefore 52/0.83 = 63; that is, a fertilizer that gets all its potassium from K 2 O and has the same potassium contents as pure KCl would have to be 63% K 2 O. Pure KCl fertilizer would thus be labeled 0-0-63.
Potash is produced worldwide in amounts exceeding 71.9 million tonnes (~45.4 million tonnes K 2 O equivalent [5]) per year as of 2021, with Canada being the largest producer, mostly for use in fertilizer. [6] Various kinds of fertilizer-potash constitute the single greatest industrial use of the element potassium in the world.
Solid fertilizer is typically granulated or powdered. Often solids are available as prills, a solid globule. Liquid fertilizers comprise anhydrous ammonia, aqueous solutions of ammonia, aqueous solutions of ammonium nitrate or urea. These concentrated products may be diluted with water to form a concentrated liquid fertilizer (e.g., UAN).
The Potash Corporation of Saskatchewan, also known as PotashCorp, was a company based in Saskatoon, Saskatchewan. The company merged with Calgary-based Agrium to form Nutrien , in a transaction that closed on January 1, 2018.
