No-dig gardening

No-dig gardening is a non-cultivation method used by some organic gardeners.

This technique recognizes that micro- and macro-biotic organisms constitute a "food web" community in the soil, necessary for the healthy cycling of nutrients and prevention of problematic organisms and diseases. The plants transfer a portion of the carbon energy they produce to the soil, and microbes that benefit from this energy in turn convert available organic substances in the soil to the mineral components the plants need to thrive.
