Description
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.

Great product, the bag leaks a touch so I recommend moving it into a plastic bin as soon as you can. (Company packaging problem not from concentrates)

What a great deal for rock phosphate. You have to be willing to pick it up from the warehouse to make the great deal a reality
