I live in the pacific northwest and our soil is mostly glacial till. It's VERY rocky and making new beds is quite a bit of hard labor. However, I managed to rig up a rock sifter with a little motor to shake it around so it's a bit more managable. Clearing beds means digging out a 3'x2' little square and dumping it through the sifter and storing it in a big bucket. Then you drag the next 3'x2' square over to the spot you removed the previous soil and run it through the sifter again. Also, have to break through the bottom layer before moving on which is a pretty solid matrix of rock and clay. Otherwise, rain water will sit on that layer and causes a lot of problems for anything with longer roots.
Ammendments depend on the crop but this were certified organic so we use all organic materials. Fish emulsion, blood meal, etc.
As far as what we've been growing.. white grapes (all gone now, going to be bottling the first bottle of wine in about a month), carrots, lettuce, tomatoes (currently 3 30'x10' hothouses), greenbeans, peas, kolrabi, corn, squash, pumpkin, onions, garlic, apples, raspberries, zuccini, jalepenos, peppers, artichoke, edamame, rosemary, cucumber, strawberries, tomatillos, blueberries, mezcla, eggplant, basil, beets.. the list goes on a bit more but I'm drawing a blank now.
We also grow a variety of flowers and such for floral arrangments. Budlia, snapdragons, sunflowers, penstemon, etc. And then there's the tree farm as well, mostly alder at the moment but douglas fir, cedar, oak, pines.. we also have a few redwoods that were planted but obviously won't get very large for quite awhile. We lost a couple of them from ruting deer who managed to pull down the fence we'd put around them. Those damn deer love baby trees.
So, anyway.. I guess this is more of a farm than a garden but.. oh well
