Just keep pulling out the stones and mowing - not very short, but often enough for it to be possible to push the mower - the more you mow the better it will be - in the past we've tamed large areas of thistley nettley grass but regular mowing with a rackety old petrol driven rotary mower. Wear good boots and protective goggles if it's stoney ground and just get at it.
I wouldn't put any fertiliser on it, but if there are large patches of nettles/thistles etc then I'd hire a knapsack sprayer and just spray those areas with glyphosate.
Maybe you can bribe/reward the children to stone-pick - I understand it was popular with farmers in Norfolk in years gone by - they got the local children to clear their fields ....... apparently they even got time off school to stone-pick ......... I'll get my coat
