Horse manure is terrible from a nutrient standpoint. A horse doesn't have much digestion take place in their stomach. Most of it is done in the "hind-gut" or colon. This means that things are digested terribly well including a lot of weed seeds. Rabbit and chicken are great. Cow and hog is good.
I know in Milwaukee WI, and I'm sure many other places, human waste is composted for Agriculture use. And of course leaf compost, grass clippings, wood chips/saw dust, expired produce (both from individuals and grocery stores) is available too. I think if someone makes it of high enough importance they could get all their inputs from local urban sources.

http://www.growingpower.org I think this company 'Growing Power' has a good urban farming model. They build their own soil, they build use and sell their own worm castings, they do aquaponics. So they sell worm casting, produce, fish, and they sell their service helping other individuals open urban farms.
Another good resource I've found on the matter is Eliot Coleman. He and his wife own a rural farm so the information he presents in his books aren't focused on urban farming, but many of his practices though I think could benefit an urban farmer. But more specifically, in his book The Winter Harvest Handbook he has a chapter on Paris market gardening in the 19th century. They used very intensive techniques and with 6% of the land Paris became a net exporter of produce. Unfortunately cars don't poop out black gold like the horses they used for transportation at the time did, and my understanding is that horse manure is the best manure to use for vegetable production, so maybe such intensive techniques aren't possible in an urban setting today (without shipping the poop in I guess). Irregardless, I haven't been able to find any extensive resources on the practice that is written in english, so I've been meaning for a few years now to get a french grammar and a french to english dictionary and pick up a french book hopefully written by one of the market gardeners themselves about the practice and the life of a market gardener to translate to english.
