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.
