Every product below is blended and supplied in Australia, and carries a full specification, the nutrient it delivers per tonne and per hectare, packing formats and 20ft container loading — plus a free technical data sheet you can download without giving us your email.

Compound grades carry the full declared ratio in every granule, so the analysis cannot separate in transit or off the spinner. High tower compounds add a harder, rounder granule that throws evenly on wide spreading widths. Blended products mix straight fertilisers to any ratio, which is what makes matching a soil test possible. Water-soluble grades suit fertigation and foliar programs, and straights are supplied alone or built into your specification.

We do not sell online — no cart, no checkout, no payment on this website. Send an enquiry and we reply with a written quotation covering product, packing and freight to your address. If no standard grade fits your soil test, ask about custom blending, or send us the report through soil test matching.

Minimum order 10–25 MT · delivered Australia-wide · shipped worldwide. Payment by bank transfer — EFT within Australia, T/T for export.

Sulphate of potash 0-0-50 supplied across Australia — chloride-free potassium with sulphur, for chloride-sensitive and quality-driven crops. SOP carries 500 kg of K2O and around 170 kg of sulphur per tonne, and essentially no chloride. That is the whole reason it exists as a separate product: grapevines, citrus, avocados, stone fruit, potatoes and berries all respond badly to chloride. On non-saline broadacre ground, muriate of potash is usually the better buy.
