Nitrophosphate fertilizer is made by digest-ing phosphate rock with nitric acid. This is the nitrophosphate route leading to NPK fertilizers; as in the mixed-acid route, potassium and other salts are added during the process. The resulting solution is cooled to precipitate calcium nitrate, which is removed by filtration. The filtrate is neu-

Complex mineral fertilisers can be produced via various processes or production routes. An important production step is the conversion of the phosphor from the natural rock phosphate into a plant available form. One of the possible processes to do so is called the nitrophosphate route or Odda process.

NPK fertilizers are used in agriculture, wielding main nutrients for plants growth. Since this compound fertilizer process the three main nutrients needed it has a significant use in soils that show deficiency and unbalance levels of nutrients.

The most widespread NPK fertilizers in Europe contain nitrate and/or ammonium salts. NPK fertilizers can be produced in four, basically different, ways:– ammonium phosphate/ammonium nitrate-based NPK fertilizers nitrophosphate-based NPK fertilizers (mixed acid route) nitrophosphate-based NPK fertilizers (ODDA-route)

A primary advantage of this method is that little or no sulfur (S) inputs are required. With the nitrophosphate process, excess calcium from the phosphate rock converts to valuable calcium nitrate fertilizer instead of gypsum. Norway pioneered the nitrophosphate method, and much of the global production still occurs in Europe. The general ...
