Lecture 35 NPK Fertilizers – Nitrophosphate Route Phosphate sources must be converted into a form which can be taken up by plants ("available"). This can be achieved by using the integrated "Nitrophosphate" process which produces compound fertilizers containing ammonium nitrate, phosphate and potassium salts. This process aims to produce nitrate-containing straight and compound ...

Nitrophosphate process - Wikipedia

The nitrophosphate process (also known as the Odda process) was a method for the industrial production of nitrogen fertilizers invented by Erling Johnson in the municipality of Odda, Norway around 1927.. The process involves acidifying phosphate rock with nitric acid to produce a mixture of phosphoric acid and calcium nitrate.. Ca 3 (PO 4) 2 + 6 HNO 3 + 12 H 2 O → 2 H 3 PO 4 + 3 Ca(NO 3) 2 ...

Fertilizer - Wikipedia

NPK fertilizers are three-component fertilizers providing nitrogen, phosphorus, and potassium. NPK rating is a rating system describing the amount of nitrogen, phosphorus, and potassium in a fertilizer. NPK ratings consist of three numbers separated by dashes (e.g., 10-10-10 or 16-4-8) describing the chemical content of fertilizers.
