I'm basing this concolusion on an article written by NC State University that states the soil in this area is so lacking in phosphorous that it is generally a good idea to add it. Not only this particular article, but advice from a professional that has been working in this area for many years and for big companies in the area. As soil is particular area by area, what other people post about levels of P won't necessarily reflect the natural soil type of Asheville's mountain soil which is naturally lacking in P, Mg, and Ca, also taken from an official NCSU article...

Furthermore most lawns in this area are infested with clovers. This is only possible because the tall fescue which is the standard grass around here cannot compete with their root systems which is a symptom of phosphorous lacking in soil.

Let's be pragmatic. If I refuse to fertilize with P, people will continue to do so because they simply don't care. If, however, I was able to find a way to minimize the risk of runoff pollution while still providing P then I would be a lot more likely to make a positive change on the issue that you bring up. The local master gardener extension states that correctly applying P will not pose a risk of pollution. Although your concerns are legitimate we need to be realistic about what will reduce phosphorous pollution.
