How It Works
Potassium and sulphur nutrition.
- Supply nutrients: Potassium sulphate, NPK 0:0:50 with 18% sulphur supplies nutrients as part of a crop feeding programme.
- Match the need: Use soil, water or tissue analysis and the crop stage to identify the appropriate nutrient input.
- Apply appropriately: Follow the crop-specific label method and measure only a clearly stated dose.
Fertilisers support nutrient supply; they are not a substitute for a complete crop nutrition plan or a registered pest-control product.

The manufacturer lists 18% S in product text and describes use in salty soil. This is not a promise to correct salinity or a replacement for a soil-specific salinity-management plan. Stage guidance: Post-flowering stage. Where the manufacturer names broad crop groups, suitability for a particular crop still needs confirmation.
Application Guide
The public manufacturer table has a combined kg/g/mL per hectare heading without a product-specific unit. Its numeric rate is therefore not reproduced as an application instruction.

Table details for every listed crop or scope: Methods — Fertigation, drip irrigation or foliar application. Stage — Post-flowering stage. “Confirm unit” and “Confirm basis” mean that the product-dose unit and the water-volume area basis must be confirmed on the current label. The source lists 1250–2500 under the combined unit heading and 1000 under a water-in-litres heading without a stated area basis. Do not turn those figures into a gram, kilogram, acre or tank dose without the current label.
Foliar concentration, fertigation quantity and an area rate are different measurements; one cannot be substituted for another.
Confirm crop suitability, nutrient analysis, application frequency, water quality and any mixture restrictions. No automatic compatibility with pesticides or other fertilisers is claimed.
How to Apply: Best Practices
- Check nutrient need: Match the crop, stage and soil or tissue result to the nutrient input.
- Verify the pack: Check the full product name, guaranteed analysis and explicit application unit.
- Use the specified method: Fertigation, drip irrigation or foliar application. Follow the supplied preparation and equipment instructions.
- Handle carefully: Avoid eye and skin contact, prevent spills and keep fertiliser away from food, feed and children.
