Product Description

Soft Rock Phosphate, also known as colloidal phosphate, is a clay material that is surface mined from the old settling basins of former hard phosphate rock mining operations in Florida.  It is a very fine material, but can be applied with all common fertilizer spreaders. Natural phosphate stays where it’s put when applied and does not move or dissolve into the soil solution. Soft rock phosphate is insoluble in water, will not leach away, and therefore is long-lasting.
