Here is one result of the Back to Eden gardening method at work by a farmer in Texas... https://www.youtube.com/watch?v=ROZzs54xLJs It's amazing how simple and natural this concept is, what's taken us so long to get it? :D This is a very good video for chicken farmers. You can also see what a fire ant hill looks like in this video. I hate those things, saw them in Alabama when we visited one time.
Actually this same farmer has a great video on making a greenhouse... https://www.youtube.com/watch?v=-DKlXs8iov0 This is a portable and inexpensive greenhouse, it's great and good video. It can also be used for a garden shed, storage,etc, instead of plastic you can put a tarp.
