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.

Out of interest, what organic mater would you rather not compost?

Mainly roots and leaves of docks, dandelions, creeping buttercup,nettles and elder. I am not too bothered whether they survive the composting process in the centre of the bean trench as I will not be moving it, just adding to it.

My dalek compost will be spread on the plot and I would rather I didn't do more harm than good.
