FUKUOKA - A Japanese agro-philosopher developed a farming practice called "Natural Farming", in response to modern organic agricultural methods that degrade soil. He encourages "no till" methods of grain cultivation, and the idea of letting nature do the farming work for you. He wrote an important book called One Straw Revolution, and introduced the idea of "seed balls", self propagating balls of clay containing hundreds of seeds, to the world: The Natural Way of Farming by Masanobu Fukuoka.

I would be very interested in hearing some practical experience with this method.
