Just to expand on what Peggysue said, you should never manure and lime at the same time (it causes a bad chemical reaction), now potatoes prefer acid soil and legumes alkaline. So if you lime the ground for your legumes, it should be the year after the potatoes were in that ground, then it will be a full rotation ( 3, 4 years depending on your rotation) before the potatoes go back in the limed soil. Also if you manured the potatoes, if the brassicas go in after the legumes, being hungry feeders, they get the benefit of the nitrogen fixing of the legumes and the manure. You can then follow with onions or root crops.
My way of remembering this is LaBORS, Legumes, brassicas, onions, roots, solanacious (potatoes,tomatoes).
There are many different rotations and I vary it in different parts of the allotment depending on the quantities of crops I want to grow, but the principle is don't manure and lime at the same time, lime after the potatoes and legumes like lime, brassicas are hungry feeders and also like lime, then the root crops and onions don't like too well a manured soil, then come the solanacious and curcubits which like a well manured soil, bringing you round the full circle.

Also remember that a lot of manure is contaminated with Aminopyralid, as too many people have discovered to their cost over the last three years. You should really do the "bean test" before you spread it on your ground.
See this page for details of the problem and the test. http://www.growyourown.info/page164.html

I'm starting new beds from scratch in a large turfed front garden and put bags of new-ish (6 weeks old maybe) straight on top of the ground once I'd taken the turf off. I didn't dig at the time as the ground was rock hard, just left the pure poo (no straw) intending to let it rot and add more on top and dig over the winter.

A few weeks later I was left with too many seedlings of french beans, peas, courgettes and sunflowers and decided to put them in this bed with about one bag of compost to help things along. I thought they'd probably die but as I had too many to even give away I thought I may as well. They're all doing fine actually, considering there was rock hard soil two inches down and pure poo above! It's not a record crop but it's fine: the peas and courgettes cropping well.

I wouldn't recommend it as a considered course of action but I don't think that unrotted poo is the dangerous subject we've always been told.

Im adding manure now as I clear beds eg early potatoes, peas + broadbeans.

Good to hear that I think that most of us don't want to try in case we ruin our crops! It's not like we all have space or time for experimental beds...

It's not something I would have done were the seedlings not dying in their pots waiting for some ground!
Though I didn't know about the chemical contamination and am a bit worried after reading that link! But I've not seen any sign of problems with the peas and beans in the bed.

If everything looks ok, then it wasn't contaminated with the broadleaf weedkiller, so that's great!
