Bio-Intensive agriculture is a millennial old production technique that uses low tech methods for food production.
Over the last 35 years John Jeavons has developed these timeless techniques into a system that can be used to attain sustainable food production. He has developed a matrix of these dimensions: calories for people and carbon for the soil in the smallest area possible using the least amount of resources. These developments are being called Grow Bio-Intensive to differentiate them from the older potentially unsustainable methods.
Grow Bio-Intensive is based on a balance of eight important elements:
* Deep soil preparation, with Raised Beds
* Composting
* Intensive Planting
* Companion Planting
* Carbon Farming
* Calorie Farming
* Open Pollinated Seeds
* Holistic Farming Method
GROW BIO-INTENSIVE mini-farming techniques make it possible to grow food using:
* 67% to 88% less water
* 50% to 100% less organic fertilizer
* 99% less energy than commercial agriculture
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.
More information on Grow Bio-Intensive can be found here and at our upcoming 5 day workshop at Ezemvelo, September 16-21.
