Turbocharge your soil with biology.

For years, the crown of our industry was N, P and K. Today, we understand biology as the key ingredient to achieving healthy soil and plants.

For decades our biologicals, including our recognized Companion® technology, have risen to this challenge on turf grasses across the U.S. and in select international markets, including London Stadium and the Watford football club. 

We are now expanding our portfolio by adapting our top-performing Ag technologies to serve the turf and ornamental markets. 


Paving the way for new growth is our game-changing turf management program BioAeration™—a specialized suite of products, including our complete biofertility solution SP-1 T&O™ — that replace traditional aeration with biology, transforming soil structure and reducing stress.

Our refined portfolio also includes Micrel Total 5-0-0, a complete micronutrient package that combines six chelated micronutrients with nitrogen to prevent and correct micronutrient deficiencies.

DPH Biologicals is proud to work with Watford FC, a Premier League team, to keep their pitch full and beautiful.
