Biological Soil Remediation: What the Science Documents and How We Put It to Work
A technical paper on biological soil remediation: how microbes, fungi, plants and biochar act on contaminants, which of the 291 microbial species identified in Elm Dirt's products are documented in peer-reviewed research against which contaminants, how we design field work, and where this approach fits and where it does not.
