Phosphate Rock is a natural, untreated soft phosphate with colloidal clay containing valuable minor minerals in addition to phosphorus. It is not acid forming, will not cake or harden and spreads easily through any type of lime, phosphate or fertilizer spreader. Phosphate Rock is not a complete fertilizer. It is an excellent source of phosphate that can be used profitably on certified organic farms. When applied to the soil Phosphate Rock adheres to and becomes a part of the soil. It will not leach and once applied, remains in the soil until used by the plants. Phosphate Rock contains no harmful acids and encourages growth of soil bacteria and earthworms.
Application Rates
In addition to supplying phosphorous for blooming flowers and vegetable gardens, Rock Phosphate also provides calcium and small amounts of trace elements. Since it contains no harmful acids associated with ordinary superphosphates, it will not harm beneficial soil organisms and earthworms. For bigger and improved root systems, apply Rock Phosphate to roses, flowering bedding plants, perenials and vegetable gardens for continuous plant nutrition.
