... adding compost or manure onto the surface of the plot. Diggers do that as well!
Digging is not the odorous task that most people assume, and it gives total control of your patch.
I think you meant 'onerous'
I have no chance of no dig method, soil type we have has every damn nasty perinial weed going, horestail being the worse, I have adopted a french method but cant find the web site I read to convince me of it, basicly I am digging the plot over again this year to clear as much root as poss, my veg will be spread over a slightly larger area with bigger gaps between the rows and a little bit bit bigger on the spacing, also this year I am not growing main crop spuds, now the theory, have invested on a little rotovator I will muck in turn it and plant, the roto will be used between crops to encourage the weed seed to come up and germinate, according to the site plants use energy form the seed/root upto 3 inches high from this point they then put energy into the root so if u turn over the weed at 2 inches youwil gradually expend its stored energy, the idea this year is to keep the ground moving, so as my summer brassicas are being harvested the gap between them gets filled with the winter and spring crops and where the summer ones have been get turned over, again same with my spuds, they will be staggerd so they are not all ready at once, over a course of about 3 years this method uses up a lot of the weed seed bank and converts it to green manure.
I`m a rotational digger ie a thorough digging over of beds when the potatoes come out
