Depends if you want organic or quick-fix really. I suppose one could plow it up and plant canes and lines and fertilize it with oil fractions and chemicals and produce lots of hops. But if you want to go green (and more delicious) don't plow it up! The soil takes years to develop it's own ecosystem which is naturally perfect for growing most anything. By plowing you destroy the fungus and bacteria cultures that hops need to grow healthy and soil to continue yielding nutrients. And your 'wasteland' sounds like it is perfect, if not a bit dry.
Start a compost system, it needn't be complicated, just two boxes covered in your garden, one for grass clippings and leaves, the other for table scraps and more 'juicy' garden waste.
First choose the spot you want, plenty of sunshine and soft loamy soil, lay a hose pipe tied off at one end over the intended patch and poke little holes in it so you don't have to water by hand. Lay canes or poles with line tied between them at picking height, you can get creative with your design at this point.
dig a 1'x1'x1' hole for every plant you want to grow, they will need atleast 4 square feet between them. Mix the soil removed with compost and fertilizer of your choice. Lay it back in the hole and water for a week.
Buy established seedlings or start your own seedlings indoors until they are strong enough to fight off bugs. then place them in your patches with a nearby cane for them to grab hold of.
Once they are in you should place a mulch of wood chips, grass clippings, rotting leaves over the soil around the base of the plant without directly touching the stem. This locks in moisture and nutrition and prevents little weeds stealing all your hops' soil.
Weed as necessary and water a little each day and they should shoot up faster than you have ever seen. First year the yield will be low but if you keep applying mulch and love the following years will give you better and better crops.
This is a very basic way to do it but if you want to go all 'serious' you should get a book on hops and gardening to realize the potential of your wasteland.
