How we make our fertilizer | Yara International

Calcium nitrate (from the nitric acid combining with the calcium in the rock phosphate) as found in the YaraLiva range. The limitation of this process is that the phosphate content of the fertilizer cannot exceed the nitrogen content. Potassium. Most potassium used in fertilizer production is taken from natural deposits of potassium chloride.

Sulfuric Acid in the Phosphate Fertilizer Industry ...

Sulfuric acid is used as a key first step in the production of both MAP and DAP, after which it is mixed with phosphate rock to produce phosphoric acid. And since the phosphoric acid production process consumes energy, an onsite sulfuric acid plant – a net producer of energy – is a critical part of the fertilizer production process.
