PhoSul was born from within the industry of fertilizers and farmers by a team of committed individuals that believed the world could do better growing more quality food with less impact to the environment.

PhoSul, LLC was incorporated in 2018 after initial trials of the PhoSul® product proved successful. Patent filing followed as well as studies by Montana State University that validated the technology and aided in product formulation. Until recently, PhoSul® was granulated at ProPeat's Fertilizer Plant in Sugar City, Idaho where the formula was finalized and OMRI registered.

On January 5th, 2024 PhoSul® signed a joint venture with Falcon Isle Resources to launch a granulation plant in Delta, Utah and gain access to Falcon Isle's local rock phosphate mine.

PhoSul® is sold in bulk to both organic and traditional farmers and can be ordered for delivery by Home and Garden enthusiasts via the Home Depot website.
