Granular rock phosphate (GRP)
CHEMICAL & SIZE ANALYSIS
Granular Rock Phosphate (GRP/RPR) is a slow-release Phosphate suitable for direct applicant with much less dissipation than Powder Rock Phosphate. Economic source of Phosphate. Enhances the PH of the soil, with benefits becoming more apparent over time as biology adapts. Has a significant amount of calcium.
As it’s 100% natural compounds, RPR is used as an organic fertilizer. Cadmium level is very low.
