This article is the continuation of a series of articles that provides producers with information that aids in phosphorus (P) management. We address the following: soil testing as a tool, trying to predict availability of P for crops, agronomic testing for P, environmental testing for P versus agronomic testing for P, and environmental perspective and interpretation.
