with this method you can cover part of your plot with un-rotted (fresh manure) that way the new manure can be left for a year to mature while the rest you cover with well rotted stuff and can work within a few weeks.
bekkie yes I've used this before, I work with schools and when we fit raised beds we put them straight onto the playing field and cover with a double layer of cardboard and then top the beds up, the beds are usually only 15cm high at the most and we get very little weed coming thru.
I've also used it on a community garden which was covered in brambles, dock and nettles, strimmed it as flat as I could, double layer of cardboard and then covered with spoiled hay and straw from a local farm. the next year we could just plant thru the half rotted hay and as long as you keep the organic matter damp (which in winter isn't hard) the cardboard is gone within 6 - 8 months. you just have to remember to remove the stick tape as that doesn't rot!
