One important thing to remember is that we often need compost to improve the physical aspects of the soil. It is primarily humus that does this. Humus is a breakdown product of OM. I don't believe that humus is any different if the compost is different. So, as everybody above has said, you need a good mix (,though this is not always possible - I use a lot of composted wood chip. One material only, breaks down to peat like product) It needs oxygen and water to activate the bacteria. The breakdown process will release nutrients but many of these will drain away and be lost. Breakdown releases humus, this is what you need in your soil.
