Rock Phosphate is a naturally occurring mineral which is ground to a fine dust to improve the release of phosphorus for plant growth. This powdered mineral is then granulated with a natural binder called lignosulfonate. This granulating process produces a consistently sized particle that is easy to apply and is completely free of dust. After application, the pellets dissolve in water, returning the rock phosphate to a powder form. In addition to its binding qualities, Lignosulfonate naturally chelates the trace minerals in the rock phosphate, helping to improve availability.
- A natural mined mineral finely ground to improve nutrient availability.
- An excellent source of slow-release phosphorus to improve long-term soil fertility.
