Crop rotation without brassicas

[Mikey & Annie]

We have clubroot in our organic veg patch. The patch consists of four raised beds which are used in a crop rotation. All the beds have clubroot and the whitefly are also very active, so we've decided to miss all brassicas out. The rotation went:- potatoes - legumes - brassicas - onions.

The question is, what could we grow instead of brassicas that would take advantage of the nitrogen nodules left by the legumes? Lettuce perhaps?

Difficult one really. But i suppose it depends on how cold a winter you get. What about cornsalad, chicory, just sown mooli.
