"To win our freedom from toxic chemicals, we must start gardening with nature. The key to gardening with nature—to true organic gardening—is to recognize the power of beneficial microorganisms, elements little known or understood by the general public."
By Dr. Elaine Ingham, Phd. in "Introduction To Gardening With Nature" article.

Soil food web - Wikipedia

Food webs describe the transfer of energy between species in an ecosystem. While a food chain examines one, linear, energy pathway through an ecosystem, a food web is more complex and illustrates all of the potential pathways. Much of this transferred energy comes from the sun.
