DescriptionLoblolly pine (Pinus taeda L.) planted in the South Carolina Coastal Plain on wetsites which had been ditched and bedded responded to P fertilization. Under conditions of severe P deficiency) tree height increased 82 percent in 3 years from application of 25 or 50 pounds of P per acre at planting. First-year growth data from four sites show that a response to P fertilization should be expected when needle content is less than 0.11 percent P 1 year after planting. As P content of the needles decreases below this level, response increases.
