soil food web

From The Lexicon of Sustainability:

Our soil teems with a multitude of organisms which provide the necessary work for healthy plants to grow free from disease, pests and infertility. These interconnected interactions and feeding relationships (quite literally “who eats who”) help determine the types of nutrients present in soil, its depth and pH, and even the types of plants which can grow.

The soil food web is comprised of the species of organisms in our soil that create an environment free from disease, pests or fertility problems.  For Dr. Elaine Ingham, the result is healthy plants and a safer environment for us to live in. In parts of the world where human impact has been massive and un-remitting, especially in the case of over-reliance on petrochemical-based pesticides and fertilizers, we are losing many needed and necessary species of micro-organisms, putting our soil’s health at great risk.  The food we grow needs to contain balanced nutrition not only for humans, but also for the animals we care about and the life that sustains us.
