Crop Rotation/Or not - Beans

This year I am trying an experiment. Weedy organic matter that I would rather not add to my compost dalek, I am just chucking it along the centre area between my been poles/canes. These are pretty substantial as they are held up by a greenhouse frame.
The theory is that as it rots down it will feed and keep the area I plant the beans. It won't be moved and should nourish the plants. Next year before planting I propose to pull some of the compost from the sides onto the sowing area and just keep adding to the central compost longhouse.

That's interesting Vinny, I have 2 daleks that are solely being used for the plot weeds this year and was going to try and utilise these somehow.

Was thinking of some sort of hotbed thingy for courgettes but may also use some for the bean area

Thanks for the idea.
