The reason for crop rotation isn't just to avoid blight.

It is a reason, but not the main reason?
Other pests and diseases?
Am I right in saying that for eg: bean plants fix nitrogen into the soil
for next years brassiccas? then potatoes, then carrots and parsnip?

A lot of questions from me. Most of us cannot have a 4 year rotation, well,
me anyway.

I often find that going back to basics work.
