"PhoSul is the most sustainable and environmentally safe method of liberating rock phosphate for agricultural production in the world."

How PhoSul Works

Grows With Nature®

PhoSul utilizes an all natural, patented process that blends phosphate rock, sulfur, and amorphous silicon into a homogenous mineral granule, is not water soluble, and does not runoff in surface water.

All Ingredients are OMRI Listed and when activated, start a microbial reaction that creates a "calcium sink" allowing the natural liberation of phosphate, making it almost all entirely plant available.

PhoSul is environmentally friendly and when applied to phosphorous deficient soils it will compete in both performance and economics with chemical produced phosphate fertilizers.

Science

PhoSul is Proven Science

Validated in the Lab, Greenhouse and Field

PhoSul has been working with four of Montana State University research stations on a variety of field crop tests (wheat and alfalfa) over the last four years at several of the MSU Agricultural stations including those at:

• Moccasin, MT

• Corvallis, MT

• Fort Ellis / Bozeman, MT

• Sydney, MT

Additional commercial field testing has been conducted on Potatoes, Alfalfa, Canola, Winter, Wheat, Spring Wheat, and a variety of fruits, vegetables, and berries. PDF reports from these tests and others can be found by clicking the "More Science" link below.

About

About PhoSul

PhoSul History

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's rock local 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.
