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]
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.
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 ...

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 ...
In a five-year study comparing before and after cases, fertilizer use in Cameroon, Senegal, Tanzania, Nigeria and Ghana declined 25-40 percent, while it increased 14-500 percent in Benin, Togo, Mali, and Madagascar. Subsidies may have been only one factor affecting the price and use of fertilizer. [4]
