Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% [1] to 20% phosphorus pentoxide (P 2 O 5). Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more ...
Phosphogypsum (PG) is the calcium sulfate hydrate formed as a by-product of the production of fertilizer, particularly phosphoric acid, from phosphate rock. It is mainly composed of gypsum (CaSO 4 ·2H 2 O).
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.
Phosphorus refers here to salts of phosphates (PO 3− 4), monohydrogen phosphate (HPO 2− 4), and dihydrogen phosphate (H 2 PO − 4). These anions readily interconvert, and the predominant species is determined by the pH of the solution or soil. Phosphates are required for the biosynthesis of genetic material as well as ATP, essential for life.
Volcanic rocks were thought to be a good source for rock powder but it was determined that it contains toxic elements as well. [3] Research has been done into phosphate rocks, but these too have the issue of containing heavy and radioactive elements. [1] The use of rock powder in remineralization has the potential to help mitigate global ...
Fertilizers are usually labeled with three numbers, as in 18-20-10, indicating the relative content of the primary macronutrients nitrogen (N), phosphorus (P), and potassium (K), respectively. More precisely, the first number ("N value") is the percentage of elemental nitrogen by weight in the fertilizer; that is, the mass fraction of nitrogen ...
