What Is Rock Phosphate Fertilizer? Uses, Benefits

However, you should sometimes avoid using rock phosphate in your garden. Rock phosphate performs more efficiently when soil pH conditions are under 5.5, so you should test your soil with a meter before adding it. If your soil pH is high, phosphorus has trouble dissolving in water. This fertilizer needs acidic soil or will sit in the ground and ...
