Why should I test with Earthfort? 

Earthfort specializes in soil biology; we believe if you can measure it, you can manage it.  We have been measuring biology since the laboratory opened in 1996.  We use proven methods of direct count microscopy which are referenced under our assay descriptions.  Our Essential test assesses the moisture level (in soils and composts), total and active bacteria, total and active fungi, presence of aerobic protozoa. We can also test for nematodes (identified to Genus), E. coli, mycorrhizal colonization, and nitrogen cycling potential, see our testing order form for details about all our testing packages. Upon receiving your testing results, Earthfort provides a telephone report interpretation for those customers new to interpreting data.  If requested, we are able to provide remediation consulting for those who want assistance on the practical application of soil amendments (fees may apply.) 

When sending 15 or more samples it’s helpful to email the tracking number and number of samples to arrive.
