Living Soil The difference between dirt and soil is life. Dirt may have all the minerals in the world, and trace elements—but without life in it (bacteria, fungi, nematodes, arthropods) it can't be called soil.

Compost Tea Take a heaping measure of bacterially decomposing organic matter suspend in water, mix thoroughly and apply to your soil and stand back. A mix of organic matter, humic acid, worm castings, and forest floor fungal spores, Compost Tea is an excellent innoculent to bring life into a dynamic, active soil base. More...
Soil is Alive Living soil produces living plants. Prove it to yourself: find a new young thriving plant in the wild, expose the soil beneath its roots and look for the tell-tale signs of life: bugs, worms, the fine white network of fungal hyphae and the white dots of fungal spores.

Eat and Poop Earthworms feed on other microbes in the soil and produce worm castings, an excellent food for all plants. They aerate the soil, increase porosity, and are a great indicator of a healthy, active, living soil.
Give and Take The roots of a plant, whether it's a carrot or an apple tree, live in a symbiotic relationship with mycorrhizal fungi which feed on the sugar that the plants roots provide, while the fungi feed the plant nutrients that it needs. The oxygen and water cycle is just the beginning. The mutually benificial relationship between plants and fungi is truly amazing.

Hyphae Irrigation Soil fungi are known to have an extensive network of hyphae that can extend for many miles in vast networks that are the largest living organism on the planet. Chemical fertilizers kill fungi and can quickly turn a living soil into dead dirt.
