Calphos POWDER Soft Rock Phosphate 0-3-0 fertilizer, 50 pound bag

Natural, untreadted soft rock phosphate and colloidial clay. 

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.

STANDARD CALPHOS

This grade is the original product that has been produced since the 1940s.  It is a finely ground product with the consistency of fine lime.  80% will wash through a 200 mesh screen.

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.
