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 ...
Phosphorus pentoxide crystallizes in at least four forms or polymorphs.The most familiar one, a metastable form [1] (shown in the figure), comprises molecules of P 4 O 10.Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing [2]).
Superphosphate is a chemical fertiliser first synthesised in the 1840s by reacting bones with sulfuric acid.The process was subsequently improved by reacting phosphate coprolites with sulfuric acid.
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.
The largest use of monoammonium phosphate by weight is in agriculture, as an ingredient of fertilizers. It supplies soil with the elements nitrogen and phosphorus in a form usable by plants. Its NPK label is 12-61-0 (12-27-0), meaning that it contains 12% by weight of elemental nitrogen and (nominally) 61% of phosphorus pentoxide P 2 O
Trisodium phosphate has gained a following as a nutritional supplement that can improve certain parameters of exercise performance. [14] The basis of this belief is the fact that phosphate is required for the energy-producing Krebs cycle central to aerobic metabolism. Phosphates are available from a number of other sources that are much milder ...
As of 2006, the US is the world's leading producer and exporter of phosphate fertilizers, accounting for about 37% of world P 2 O 5 exports. [13] As of December 2018 [update] , the world's total economic demonstrated resource of rock phosphate is 70 gigatonnes , [ 14 ] which occurs principally as sedimentary marine phosphorites.
Heavy use of phosphorus fertilizers and their runoff have resulted in eutrophication (overenrichment) of aquatic ecosystems. [111] [112] Natural phosphorus-bearing compounds are mostly inaccessible to plants because of the low solubility and mobility in soil. [113] Most phosphorus is very stable in the soil minerals or organic matter of the soil.
