Soil Biology Under the Microscope: Practical Applications for Gardeners

Seeing the Invisible Garden The soil food web — the community of organisms that drives fertility, disease suppression, and soil structure — is largely invisible to the naked eye. But a basic compound microscope ($150–300 for a functional model) opens an extraordinary window into this invisible world, allowing you to assess soil health and microbial diversity in ways that no chemical test can replicate. This is the approach taken by leading regenerative agriculture researchers and is increa…
