Why would you want soil and newspaper next to each other, sandwiched between two sheets of polyethylene?

Joel: has mustard flour been used in this sort of way before? I tried to look it up but couldn't get past a trillion food related sites. It piqued my curiosity because of the fairly new discovery that sticky rice was a major ingredient in the building of very old chinese temples roads, bridges etc. one of which is still so strong that apparently it was impossible for a bulldozer to deal with it. It would be good to know if there was something which had the same sort of potential that can be grown in our climate.Sorry this is off topic wasn't sure how to address the question if I started another thread.

Here's a crazy idea, inspired by science:
For layer #4, collect some standing-dead wild mustard, thresh it, and mill the seeds into a flour, which is then (carefully! it can blind you) dusted between the layers of newspaper.
Then, if the newspaper does happen to get wet, it is immediately treated with a strong antimicrobial agent. Also, the thickening properties of the ground up seeds will help it to seal together into an impermeable layer.
The mustard powder will also tend to keep larger things, like insects, out of the paper.
By the way, wild mustard tends to be stronger than the tame stuff.
