Manure and Root Crops, and Rotation

I like the theory behind no dig but, also like an open trench for my beans I’ve never been able to marry the two schools of thought into a coherent practise.

I like the theory too but I don't have a supply of manure/compost or whatever to cover the garden a couple of inches deep every year so my plants have to get by on whatever they can find in the existing soil. If they're lucky they'll get a handful of chicken manure pellets at planting out time.
