Abstract:

Thirteen-year growth of planted loblolly pine (Pinus taeda L.) was examined on 9 poorly drained Lower Coastal Plain sites following bedding and/or application of phosphorus (P) at time of planting. Fertilization dramatically increased height and diameter growth during the first 13 years on all 9 study sites. Height and diameter growth were consistently better in fertilized and bedded plots than in flat-planted, bed-only, and fertilizer-only plots. Comparisons of height growth curves indicate that differences between fertilized and nonfertilized plots are continuing. Foliar and soil P levels in fertilized plots at age 13 suggest that growth on these sites may be increased by additional applications of P. Projection of response to rotation age indicates that the combination of fertilization and bedding results in the greatest total cubic-foot volume and after-tax net present value. South. J. Appl.
