I use aged/composted steer manure as well as chemical fertilizers and have never done a comparison with/without, but like to use it as it adds organic matter to my moderately heavy soil (silty clay loam) and nitrogen at the same time. I don't believe there is enough nitrogen to be the sole sore of nitrogen. Since my soil has high levels of phosphorus (bananas don't need much anyways), I've been fertilizing with potassium nitrate. I think the price has gone up a lot since the last time I bought it, it cost me $88 for 100 pounds a couple of weeks ago from my ag supplier. While nitrogen costs have come down some, potassium remains very high.
