Rotation

Is it feasible to use a 2 year crop rotation for potatoes and onions ? This is a continuation of my previous question. For various reasons I don't wish to use containers.

 

My experience is that rotating crops is a good idea, but it's also possible to grow without rotating - my spuds have been in the same place for a few years, for example, with no problem.
I personally would be ok to rotate spuds and onions - I'd be putting manure in, and keeping an eye on diseases.

Charles Dowding has a no rotation trial video here:
October 2017, trial results of no rotation & no dig, autumn harvests, polytunnel cropping, sauerkraut

 

The problem with potatoes in particular is that they are subject to a lot of soil borne issues, scab, blackleg, eelworms etc. An ex work colleague of mine only had space for 3veg beds but stuck to a 4 year rotation. This meant he didn't grow crops like potatoes once every 4 years. Not sure I could be that disciplined.
Having said all thst if you look at the writing of Charles Dowding, the no dig exponent. He claims by adding compost on top of the bed means you don't have to be so rigid about crop rotation. For potatoes he places them on the surface and puts compost on top. As they grow he "composts up" (his words) basically piles compost on top, to harvest he simply pulls the whole plant up. Never tried it myself. Goes without saying you need an awful lot of compost.
I don't think this method would protect onions from while rot though.

Thanks for your replies, food for thought. You've given me great encouragement Stephen.
I'll give it a go for two years then decide whether to proceed further.
