Eco Prime^® Natural (SF12) is a prilled Soft Rock Phosphate based fertiliser impregnated with Eco-Advance^® beneficial biology.

Phosphorus availability and speed of delivery is increased through to utilisation of of colloidal soft rock, palagonite, lime, rock minerals and gypsum which is ground to a fine powder and reconstituted into a prill inoculated with Eco-Advance^® beneficial biology, including Phosphorus stabilisers Bacillus megaterium, mobilisers VAM spp and plant Phytohormone producers that help stimulate root growth.

Bio-phosphate is typically not bound by high PBI soils, resulting in increased Phosphorus availability with continued use.
