'Normal' compost is just a fine you know - as long as you bring composted material to the soil; with it you bring life (little insects, good fungae,...) and the soil needs life more than 'fertilizer' there is quite some of the nutrients already in the soil, sitting there, unavailable for the plants in their 'raw' form. When you bring life you bring micro-organisms that make the nutrients available and the plant surroundings is improved so that it can cope with the unhealthy a bit more. Some call this bogus, BS or many other things - most of them or using 'miracle grow' or other 'magic from a box' fertilizer (mostly blue). When I visit some gardens I see a lot of soil that looks 'dead' the plants only seem to survive on their 'baxter' of fertilizers; when I visit some other gardens (as well my own) where compost geeks feed the soil instead of the plants you actually see life : on the soil, in the soil, what the heck even on the plants - I don't mind insects on my vegetables, I get quite uncomfortable when I see no insects at all...
Composting manure is one of the best ways to use it, I appreciate my chickens even more for their poo than for their eggs ;-)
just try it, give it some time (a season or two) and you will see the garden go better year after year. Making good compost is quite some work though; the easy way (dump it on a pile and wait) will eventually give you something to work with, but if you help the process a bit you have good results with no smell within a year...
Fertilizers (organic and chemical) are expensive so what do you have to loose ??
