Rock phosphate is the raw material used to manufacture most commercial phosphate fertilizers on the market. In the past, ground rock phosphate itself has been used as a source of P for acid soils. However, very little rock phosphate is currently used in agriculture due to low availability of P in this native material, high transportation costs ...

How to Use Rock Phosphate Fertilizer In Your Garden

To use soft rock phosphate properly, always incorporate it into the soil before planting. You can also add it to a planting hole when repotting or planting trees. Adding it to the soil surface may not be as effective. If you have a well-established lawn and trees, scatter the rock phosphate over the landscape.
