(Add) Siobhan Lavelle, I see you are in Ireland. I suspect you have dandelions but maybe not burdock but there are probably other weeds with powerful taproots you might utilize. Such things are often considered bad and can most certainly be so, but by watching their life cycle it isn't hard to learn how to control them and use their very tenacious qualities to your advantage. Also your talking about 12 acres, some of what I do might give you some ideas for a vegetable garden but don't know how it would work on such a large area. I only maintain along with the garden about two acres total, the rest of my land is mostly steep hilly woods where I plant grapes, berries and nut trees, I don't have livestock except the occasional chicken or turkey.

I'm not sure what you mean about how limestone soil should be fertile. Lime is primarily used to alkalize overly acid soil as well as secondarily to add calcium (and sometimes a fair bit of magnesium, depending on the makeup of the specific stone.) Most limestone soils, from my reading, are overly alkaline, which means most plants are not able to uptake nutrients. From what I've heard, trying to adjust the pH of lime-based soils is one of the most difficult things you could try to do. I know that Steve Solomon's The Intelligent Gardener includes a section on amending lime soils, but I skimmed that section since it doesn't apply to my situation.
Hi Mathew, thanks for that. I know alakalinity locks up soil nutrients but I read in The Intelligent Gardener that, because it's so soft, limestone leaches a lot of ntrients and if you can just amand the pH, fertility should be very high. Our soil pH ranges from 6 to 8.1. It's acidic in places and neutral in places. The acidity is due to chemical use by the previous owner. Yet fertility is low everywhere.
