Compound (NPK) and straight fertilizers in granular form for soil application — the broadest category in the Spirfert portfolio, covering the full macro and secondary nutrient range.
Fully soluble compound (NPK) and straight powders for fertigation, drip irrigation and foliar application — high-purity crystalline grades with complete solubility.
Ready-to-use liquid concentrates for fertigation and foliar nutrition, including chelated micronutrients.
Plant biostimulants based on seaweed extracts, amino acids, humic and fulvic acids — for stress tolerance and crop quality.
Most programs combine more than one form. Here's the reasoning importers and distributors typically use when matching a form to a market.
The default for soil-applied programs at scale. Lower cost per unit of nutrient, straightforward logistics in bulk or big bags, works with standard spreading equipment.
For growers running drip or fertigation systems. Fully dissolves with no residue, and lets the nutrient mix be adjusted through the season as crop needs change.
Ready to use, no dissolving step — the easiest form to meter accurately for foliar spray or fertigation, especially for micronutrients needed in small, precise quantities.
Not a substitute for NPK nutrition. Used alongside a granular, soluble or liquid program to improve stress tolerance, root development and nutrient uptake.
