Key Benefits:
- Sustained release
- Suitable for low/high PRI soils
- Biologically activated

Eco-Prime® prilled Soft Rock Phosphate biological fertiliser is impregnated with beneficial biology. Designed to enhance the soil by providing balanced Phosphorus and trace nutrients including plant available Silica.
Phosphorus availability and speed of delivery are increased through the utilisation of colloidal soft rock Phosphate, which is ground to a fine powder, and then reconstituted into a prill inoculated with beneficial microbes; designed to enhance Phosphorus release and availability.
Eco-Prime® Soft Rock Phosphate fertiliser is typically not bound by high Phosphorus Retention Index (PRI) soils, resulting in increased Phosphorus availability with continued use.
Eco-Prime® Soft Rock Phosphate is also suited to highly acidic / aluminium-rich soils, where it can provide additional pH buffering.
