Straw Bale Culture
The One Straw Revolution by Masanobu Fukuoka. Accessible Gardening: Straw bale gardening: no weeding, no hoeing, no tilling. For those of you who may have physical limitations doing tradtional gardening, you may want to try straw bale gardening.
Even wheel chair-bound folks can take advantage of this method. I've been a traditional gardener all my life, but tried straw bale gardening last year as well.
