Sounds good, you will have less woodlice and less slugs, although the soil sounds tricky. My experience of white rot is that undug soil tends to contain it to smaller areas (as opposed to it being dispersed more by cultivations) and it does diminish over time – years! – and that compost on top helps promote more health and vitality in growth.
With boggy soil I woud import as much compost as you can find at this stage (say 2-6 inches) to create a better drained and fertile medium for roots to develop, from where they can then explore your improving soil below, where worms will get busy and breed, as well as lots of other helpful soil-life developing.
I hope you can find a reasonably cheap source of old manure for example, rather than bags of compost. Good luck.
