Abstract:A field study on the infertile and droughty Lakeland sands of west Florida indicated that bedding or fertilization (134 kg P/ha as ordinary superphosphate and 90 kg N/ha as ammonium nitrate) or both increased early growth of planted slash pine (Pinus elliottii Engelm.). Throughout the 6-year study, best growth was obtained when the treatments were combined, resulting in 6-year-old trees averaging 3.0 m in height, 4.3 cm in diameter (dbh), and containing 2690 cc of stemwood volume. These values represent increases in the respective parameters of 31, 54, and 76 percent over the control. Bedding + fertilization was also responsible for a significant shift in height class distribution, which was reflected in a greater number of larger trees per unit area. Foliar P levels were higher for trees on fertilized plots for the first 3 years after treatment, while foliar K levels were higher on bedded plots the first 2 years but lower the third year. Foliar N levels were not influenced by treatments. Forest Sci. 19:135-138.
