Nitrophosphate — Combined N & P from the PASP Process
Nitrophosphate fertilizer produced via the phosphate-ammonia-sulphuric acid (PASP) route delivers 20% N and 20% P2O5 in a single granule with inherent sulphur co-product benefits. The process creates ammonium phosphate compounds with excellent physical granule strength for bulk handling and blending. Particularly effective on acidic soils where conventional TSP application gets fixed by aluminium and iron oxides. From 1,000 MT.

Manufacturing & Logistics
Nitrophosphate granules from PASP plants have superior hardness compared to pipe-cross granulation, reducing dust and fines during bulk vessel loading. Standard shipment in 50 kg PP bags or bulk; 2–4 mm size range matches most spreader equipment. Total nutrients 40% min per granule analysis.
FAQ
What distinguishes nitrophosphate from MAP or DAP?
Nitrophosphate contains partial sulphur as calcium sulphate from the PASP process, adding secondary nutrient value. Its phosphorus is in ammonium phosphate form rather than the concentrated P2O5 of MAP/DAP, giving slower but more sustained release on acidic soils.
Is nitrophosphate suitable for NPK blending?
Yes. NP 20-20 serves as a balanced base in compound NPK formulations, particularly grades where moderate P content is desired without the high analysis of DAP. Blends cleanly with MOP and urea in rotary drum granulation.
Which regions primarily consume nitrophosphate?
Northern and Eastern Europe, Russia and CIS countries have the largest nitrophosphate consumption due to established PASP production infrastructure and acidic soil conditions that favour this product type.
