It can be used as an amendment to soil, water, or sprayon product. Phosphates are essential for plant growth and nutrition. They are also crucial for keeping soils fertile, preventing erosion, and controlling plant pests. Rock phosphate is not burned off during combustion like other fertilizers, so it does not emit harmful pollutants into the air.
