The earth beneath a city block is much different than the earth beneath a lush forest. Wherever vegetation naturally flourishes, a teeming world of soil microbes undoubtedly lies below. These communities of hard-working organisms are as fascinating and diverse as, for instance, those found in the sea.

The vast array of marine life hidden throughout the oceans of the world is invaluable to the sustenance of land-based ecosystems and the same is true in regard to soil microbes. Bacteria and fungi are just a few classifications of organisms that share intimate relationships with the plants we depend on, knowing how to maintain their populations is key to maximizing the results of an organic crop.
