For my first documented progress I will show the beginnings of bed preparation.
To prepare it is easy as pie because there is no preparation!
All you do is lay out a paper or cardboard barrier and roll out mulch over it.
PS As you can see, I just pushed the roll of hay myself by hand. It unrolls easily. However in maintaining principle 5 "Capability to be mechanized for large scale or low labor for smaller scale", a bar could be inserted in the roll of hay and pulled behind a tractor for larger scale. I also laid down cardboard boxes by hand, but again for larger scale a commercial sized roll of cardboard or paper could be unrolled behind a tractor just in front of the hay. This would allow mechanization of the whole process. The labor is low, but it is even lower using a tractor, if you have larger acreage.
