Why Granulock SS
More sulphur. More performance. More productivity.
Granulock SS delivers a precise blend of phosphorus (P) and sulphur (S) in uniform compound granules, ensuring consistent nutrient delivery and even application across the paddock.
Containing sulphur in two forms – sulphate for rapid uptake and elemental sulphur for gradual release – Granulock SS supports early establishment and ongoing plant health.
Ideal for cereals, oilseeds, and pastures, Granulock SS is specifically designed for sulphur-responsive soils, helping growers avoid nutrient deficiencies that can limit early growth and yield potential.
This balanced formulation provides reliable nutrition throughout the season, supporting strong establishment and even crop development.
Best for:
- Sulphur-deficient soils and high sulphur-demanding crops
- Cropping programs using low-sulphur fertilisers such as MAP, DAP or urea
- Pasture establishment, over-sowing, and direct drill systems
- Growers seeking uniform nutrient delivery with less handling complexity
Overview
Granulock SS adds a sulphur-rich option to the trusted Granulock line up. It delivers all the ease of application and high performance you expect from Granulock fertilisers, now with enhanced sulphur for crops with elevated demand. It’s a simple, effective way to stay ahead of nutrient deficiency risks.
Consistent performance
With every nutrient in every granule, Granulock SS ensures even application, promoting uniform crop establishment and growth. From application through to harvest, it supports better yield outcomes and optimised nutrient use.
Built for productive farming
Purpose built to meet the evolving needs of Australian growers, Granulock SS makes application straightforward and effective. It’s a key part of building a nutrient program that delivers season after season.
The Science
Granulock SS is a fully granulated compound fertiliser containing nitrogen (N), phosphorus (P) and sulphur (S) in every granule.
Sulphur is present in two forms: 8% elemental sulphur and 4% sulphate sulphur.
The sulphate fraction is immediately plant-available, while the elemental sulphur is oxidised gradually by soil bacteria (Thiobacillus) to provide extended supply.
This dual-action delivery ensures that sulphur is available throughout key crop growth stages, reducing deficiency risk and enhancing nutrient uptake efficiency.
Backed by science. Proven in the field.
Granulock SS is formulated through true compound granulation processes, ensuring each granule contains a consistent nutrient ratio. This prevents nutrient segregation during handling and application.
With our Nutrient Guarantee, you can trust Granulock SS to deliver exactly what’s on the label. Routine quality control testing across our supply network ensures the specifications are met every time, providing reliable, consistent nutrition for your crops.
