NPK 19-19-19 — Premium Balanced Grade for Export Crops
Approaching the practical ceiling for balanced NPK analysis, 19-19-19 at 57% total nutrients minimizes freight cost per kg of applied nutrition. Favoured for export-quality potato, citrus and table grape programmes where balanced early nutrition sets the foundation for grade-out and sizing. Popular in Chilean, Egyptian and Moroccan export agriculture. From 1,000 MT.

Export Crop Use
Potato seedbed preparation uses 19-19-19 at 350–450 kg/ha incorporated before ridging. The equal ratio supports stem and root development during the critical establishment window before tuber initiation switches nutrient demand toward potassium.
FAQ
Is 19-19-19 available with sulphur addition?
Standard grade contains no added sulphur. Sulphur-enriched variants (e.g. adding 6–8% S from AS) can be produced on campaign order for rapeseed and onion programmes.
How does granule hardness compare to lower-analysis NPK?
Higher-analysis NPK granules from modern pipe reactors typically have equal or better hardness than 15-15-15 — less filler material means denser, more durable granules with fewer fines during handling.
Can 19-19-19 be used in organic-coated (controlled-release) production?
Yes. 19-19-19 prills serve as the core for polymer-coated CRF products. Specify granule size and crush strength requirements when ordering for coating line feed.
