Calphos 0-3-0 fertilizer 50 pound bag 

Natural, untreated soft rock phosphate and colloidial clay. OMRI approved

Calphos 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.

Calphos is not a complete fertilizer and should never be used as such. It is an excellent source of phosphate that is being used profitably for farmers who are interested in getting a dollar’s value for a dollar spent. When applied to the soil Calphos adheres to and becomes a part of the soil. It will not leach and it will not revert and once applied remains in the soil until used by the plants.

Calphos contains no harmful acids and encourages growth of soil bacteria and earthworms.
