Our Testing Services

At EarthFort, we believe that healthy soil is the foundation of healthy ecosystems.

Our soil testing services help land owners, family farms, and any small-scale grower to make informed decisions about their soils, composts, and liquids. We test for key parameters: Fungal Biomass, Bacterial Biomass, pH, Electrical Conductivity, Active/Aerobic Fungi, and Protozoa to give you a comprehensive view of your soil health.

*If you plan on bulk testing 20+ samples, please first give us a call at +1 (541) 257-2612 or email us at
