Soil samples to a depth of 60 inches were taken in a Pineapple orange grove on an acid, sandy soil after 13 years of differential fertilization with superphosphate. Data derived from these samples showed that the largest increase in P was in the top 12 inched of soil, but some increase was noted at all depths, the total weight of "feeder" roots in the 60 inches was nearly one-third less in the high phosphate plots than where none was applied, appreciable acidity was imparted to the soil by the superphosphate, particularly in the top 12 inches, and there was somewhat more exchangeable K found as a result of increased phosphate but the exchangeable Ca and Mg were unaffected and there were no differences in the total amount there were no differences in the total amount of Cu, Zn, or Mn regardless of treatment. |
