The problem is every-time you dig over the soil you are bring weed seeds to the surface and they germinate-I am a bit confused as to why you keep digging it over-have you actually tried growing something in the area?
No plant that I am aware of will get rid of weeds-you seem to be hinting at green manure perhaps- but that is more digging in
If you hoe off the weeds as they appear that is a good control-pernicious weeds like dandelions need pulling out or treating with a weed killer.
What sort of veg do you want to grow?
