Small organisms, LARGE impact

A single teaspoon (1 gram) of rich garden soil can hold up to one billion bacteria, several yards of fungal filaments, several thousand protozoa, and scores of nematodes. OSU 2010

Composting is our opportunity to contribute to the health of the soil food web while managing a "waste" product.
