Hops are nitrogen hogs while the bines are growing, but soil varies so much, it's tough to say what would work best. My 'soil' is a lot like modeling clay, except stickier. It is acidic and deficient in every nutrient I tested; except potash (aka wood ashes). When I planted, I used a mix of soil, peat moss, compost and Vermiculite. I use a dilute solution of Miracle Grow with each watering. This is in addition to lime, compost, moldy hay, blood meal and bone meal that were applied a few months ago.
So far, my home-grown hops have cost about $15/ounce.
