What is Bio-Intensive Gardening?

A sustainable solution for growing food. Most life in nature occurs at the interface of soil, water, air and sun. Grow Bio-Intensive soil preparation practices create growing beds with more surface area to maximize the effect of nature’s life processes. Double-dug beds, with soil loosened to a depth of 24 inches, aerate the soil, facilitate root growth, and improve water retention. The health and vigor of the soil are maintained through the use of compost.

Close plant spacing is used to protect soil microorganisms, reduce water loss, and maximize yields. Companion planting facilitates the optimal use of nutrients, light and water, encourages beneficial insects and creates a vibrant mini-ecosystem within the garden. A focus on the production of calories for the farmer and carbon for the soil ensures that both the farmer and the soil will be adequately fed and that the farm will be sustainable. The use of open-pollinated seeds helps to preserve genetic diversity and enables gardeners to develop their own acclimatized cultivators. All of the components of this system must be used together for optimum effect and to avoid depleting the soil.

Bio-Intensive mini-farming techniques make it possible to grow food using:
67% to 88% less water
50% to 100% less fertilizer
99% less energy than commercial agriculture, while using a fraction of the resources.

These techniques can also:
Produce 2 to 6 times more food
Build the soil up to 60 times faster than in nature, if properly used
Reduce by half or more the amount of land needed  to feed the same amount of people.
