Natural Rock Phosphate works synergistically with Mycorrhizae and is friendly to all soil organisms. Chemical forms of Phosphorous can damage Mycorrhizae and other beneficial soil organisms. Natural Rock Phosphate is mined in Montana and ground into an extremely fine powder and then formed into prills or granules with an all natural water soluble binder, making it easy to spread. 


Application rate is 2 to 4 pounds per 100 square feet.
