For 35 years, EarthWorks agronomists have asked turf managers: What’s the most important nutrient in turf management? The answer is oxygen. Without oxygen in the soil, beneficial microorganisms can’t thrive—and healthy soil biology is the foundation of strong turf.

The concept of Food as Medicine has been central to Biological Soil Management, drawing a clear connection between human health and turf health. Just as proper nutrition helps our bodies build natural immunity and resist disease, balanced fertility programs help turf recover from stress, develop stronger roots, and support healthy soil biology.
