When you choose PhosAgri, you receive more phosphorus in less volume, allowing for easier handling and faster application. Our Utah location allows for easy distribution across the US and Canada.


Low Heavy Metals

Some rock phosphate sources contain dangerous levels of heavy metals, that are harmful to both human and environmental health.

Rigorous laboratory testing has shown that PhosAgri contains low levels of heavy metals, which has allowed Falcon Isle-PhosAgri to be approved for organic production by OMRI, WSDA, and CDFA.

When you use PhosAgri, you can be assured that you are applying the highest quality organic plant nutrients available.


Beneficial Nutrients

Providing More Than Phosphorus

Along with providing phosphorus, PhosAgri also supplies a variety of other essential nutrients including calcium, iron, magnesium, silicon, and sodium.  By applying these often overlooked trace minerals, you help balance the soil and increase plant health.



With over 25% calcium oxide (CaO), PhosAgri is a great source of calcium. This mineral is essential for the formation of cell walls and cell membranes. Without enough calcium, plants exhibit weak stems and roots as well as distorted new growth


Minor Minerals

PhosAgri contains a number of important secondary and trace minerals.


Magnesium is an essential part of chlorophyll and therefore necessary for photosynthesis. Sulfur is required for protein synthesis as well as the formation of chlorophyll. Iron is involved in the formation of chlorophyll as well as DNA synthesis and respiration. Zinc is involved in enzymatic activity as well as gene expression.

PhosAgri contains all three of these essential elements and more.
