Subject: RE: More Kinsey/Albrecht discussion optimum P levels



Soil test levels of phosphorus and potassium are normally reported as elemental P and K. In contrast, recommendations are normally given as P2O5 and K2O.

A target level of 100 pm P for grain crops seems like an error.

I recommend that you speak with an agronomist at the lab and ask for clarification.
