I guess technically I'm one of those fertilizer salesmen you don't want to hear from. We would tell you you're in great shape on P and probably would not suggest broadcast on the area of the field where you have 85#...particularly assuming that is your P1 level. Your P2 is going to be higher, and perhaps significantly higher. You need to look at your K base saturation level relative to the other cations and how that works into the balance. Base % K should be between 2.5%-5.0%.
