Description
NPK 19-9-25te is a compound fertiliser: all three major nutrients manufactured into a single product at a fixed ratio, rather than blended from separates. You buy one analysis and spread it once. That is the convenience, and it is also the limit – a compound cannot be adjusted, so it suits a soil whose test the ratio already fits. Where the test points somewhere else, blending to that ratio wastes less. Potassium leads at 25%, with 19% nitrogen and 9% phosphorus. Potassium governs water regulation, stem and stalk strength, disease tolerance and – in fruiting and root crops – size, firmness, sugar and shelf life. A potassium-dominant analysis is a fruit-fill and finishing product, and it is also the correction for the potassium depletion that follows repeated high-removal crops. 53 units in total. Supplied bulk, in bulka bags or bagged, from 10 MT. Delivered Australia-wide and shipped internationally, with a Certificate of Analysis and Safety Data Sheet against the batch supplied.
NPK 19-9-25+TE Specification
Tower-granulated compound. Every granule carries the full declared ratio, so the analysis cannot separate in transit or spreading. The declared analysis and supply detail for NPK 19-9-25+TE are set out below. A Certificate of Analysis is issued on request against the batch you actually receive.

Where NPK 19-9-25+TE Is Used
Quality, fill and finishing
Potassium leads this analysis, making it a finishing and quality product rather than a growth-push product. Typical use is the reproductive phase — fruit fill, tuber bulking, grain fill — and in crops where potassium removal at harvest is high.
Packing and Quantities
NPK 19-9-25+TE is supplied in bulk, in 1,000 kg and 500 kg bulka bags, and in 50 kg and 25 kg bags. Minimum order is 10–25 MT, depending on the product and the destination. Packing formats, 20ft container loading figures, and bagging and marking are set out in full on our Delivery & Freight page.
Handling and Storage
Store NPK 19-9-25+TE dry, off the ground and out of direct weather. Nitrogen and ammonium-based fertilisers draw moisture from the air and will cake if left exposed — full handling and storage guidance is on the Delivery & Freight page.
NPK 19-9-25+TE Data Sheet
A Certificate of Analysis for your delivered batch and the Safety Data Sheet are both available on request. The analysis in the data sheet is the nominal specification; where a Certificate of Analysis is issued for a batch, that certificate governs.
