For "here", I'm basing my P recs on my agronomist, as well as Purdue university info. Purdue claims no needed P apps over 25+ppm soil test.
Sorry, I am not smart enough to know the difference between the stong/weak & Olsen/Bray. I just average the P's out and go from their with a half way educated rec. |
