One of the most difficult challenges gardeners face is that of trying to grow plants in rocky soil. Imagine placing a seed onto a stone slab and expecting it to take root. Logic dictates that a plant won't grow on a rock slab, and the same holds true even if the rock is just under the surface of top soil. Since roots require nutrients from soil to grow, along with sun and water, plant roots cannot penetrate through rock to find the nutrients and water they need to survive. So, what can you do if you discover that your soil is rocky? While you can take extreme measures and hire a backhoe to burrow through rock, or even more drastic, blast through the rock, even those procedures might not alter the soil to the degree plants need to grow.
Instead, consider supplementing the existing topsoil with more soil to create at least a foot of growing soil above bedrock. The steps to amend soil for growing are simple enough. Follow these steps to amend rocky soil to create a perfect growing environment:
While you could simply apply a layer of composted material and soil over the compacted rocky soil, doing so is counterproductive since the roots of plants go in search of water and food. The roots won't penetrate the rock and will, instead, wither and die. It is much better to take several months or years creating a perfect layer of growing material for your plants, rather than to rush and just have a few inches of pretty—but unusable—top soil.
You may also consider working with what you have and find plants that will grow in rocky soil. Visit your local extension office, or speak with the staff at a qualified nursery to determine which types of plants will grow in your local rocky soil, appropriate for your growing zone.

Your method is not practical as I am talking about acres of clay with shale in every inch of it. BUT there are farms in the area that are productive. Do I disk or what. thx

I agree, we have very rocky soil because our land used to be a river bed. I have tilled it several times, removed large rocks, added several layers of mulch, compost, peat moss, perlite, and mulched leaves. I'll keep adding until I have at least a foot of this kind of medium over the rock. In winter, I either cover with black plastic or mulched leaves because the heat composts way down into the soil and softens it. But it is a tough medium to start in, what a lot of sweating went into that initially. Now it's beautiful
