Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation: [2]
The venture was set up to produce granulated urea and di-ammonia phosphate (DAP) in Pakistan, aiming for daily outputs of 1,670 metric tons and 1,350 metric tons, respectively. [18] In 2002, the government of Pakistan paid Rs. 5 billion to Fauji Jordan Fertilizer for non-implementation of the provisions of Fertilizer Policy 1989. [19]
Its product line also includes phosphate and potash-based mineral fertilizers, as well as complex and specialty mineral fertilizer products. [ 3 ] [ 4 ] [ 5 ] The company was established in 1905 as Norsk Hydro — the world's first producer of mineral nitrogen fertilizers — and de-merged as Yara International ASA on 25 March 2004. [ 6 ]

The diagram below shows fertilizer consumption by the European Union (EU) countries as kilograms per hectare (pounds per acre). The total consumption of fertilizer in the EU is 15.9 million tons for 105 million hectare arable land area [51] (or 107 million hectare arable land according to another estimate [52]). This figure equates to 151 kg of ...

[2] [3] Founded in 1920, the company has grown to become the world's largest producer of phosphate and phosphate-based products and it is one of the largest phosphate, fertilizer, chemicals, and mineral industrial companies ...
Atlas Agro plans to build the first-ever carbon-free fertilizer production plant for a cost of $1.1 billion on the land on 150-acres on the northwest corner at the intersection of Stevens Drive ...
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.
