PHOSTONE™ is a premium, sustainable fertiliser produced from recovered struvite—a naturally occurring phosphate mineral recovered from wastewater. It provides three important plant nutrients: phosphorus (P), nitrogen (N) and magnesium (Mg), helping growers support crop development while reducing reliance on conventional mined phosphate fertilisers.

Its slow-release nutrient profile allows PHOSTONE™ to release nutrients progressively as plants need them. The product is sparingly soluble in water but fully citrate soluble, helping to reduce nutrient losses through leaching and runoff while maintaining nutrient availability in the root zone. With a low salt index, it is gentle on plant roots and suitable for use in a range of agricultural and horticultural applications.

PHOSTONE™ can be supplied in different granule sizes to suit varied farming practices, blending requirements and application methods. Its long-lasting phosphorus availability may reduce the frequency and volume of fertiliser applications compared with conventional commodity fertilisers.

More than a fertiliser, PHOSTONE™ is a circular-economy solution. By recovering valuable nutrients from wastewater and returning them to agriculture, it helps turn a waste-management challenge into a high-value resource for productive, resilient and environmentally responsible farming.
