Superior - Model SF 12 / SF 12+K -Granular Fertiliser

SF12 and SF12+K are BFA registered prilled Soft-Rock Phosphate and Potash fertiliser, impregnated with beneficial biology. Phosphorus availability and speed of delivery is increased through the utilization of colloidal soft rock phosphate, palagonite, coal fines, lime and gypsum which is ground to a fine powder, then reconstituted into a prill inoculated with beneficial microbes; including phosphorus solubalisers Bacillus megaterium, mobilisers VAM spp and plant Phytohormone producers that help stimulate root growth. Bio-phosphate is typically not bound by high Phosphorus Buffering Index (PBI) soils, resulting in increased phosphorus availability with continued use.
