Abstract
Synopsis: The rate of depletion of soil phosphorus and potassium when omitted from the fertilizer increased with increasing rates of nitrogen application. Potassium became critical sooner than phosphorus on the Tifton loamy sand. Maintenance fertilizer consisting of a 4‐1‐2 ratio produced hay yields equal to those resulting from higher amounts of phosphorus and potassium.
