It is a very good and interesting article. Thank you for posting the link kimmq.

Here are two more articles on the same topic, both could be of great interest to the organic gardener:

Soil Biology in the Key to Healthy Soil

Soil Food Web

I have posted links to the Soil Biology Primer (your Soil Food Web) many times here, but I will need to spend some time with the Key to Healthy Soil. Thanks for that.

The article on Soil Biology in the key to Healthy Soil pretty well summarizes everything I learned about soil since the 1960's. A good refresher read.
