|The USDA's Soil Biology Primer
The Soil Biology Primer provides
information on the types of organisms
present in healthy soil along with their role
in the Soil Foodweb.
This is recommended reading for anyone
looking to transition to organic soil
management, or just looking for some
background information on what makes
healthy soil healthy.
