I've been researching P lately and looks like under 10 ppm you will likely get a response. Between 10 and 15 ppm its a toss up if you will see a return to a P application. Above 15 ppm its unlikely to get a return on a P application. That data was taken with more profitable grain and fertilizer prices so probably even lower with today's prices.
