A Review of the “Pull-Up” and “Leave-Down” Methods of Planting Loblolly Pine

June 8, 2021 - Article provides a review of the research and science behind two approaches to planting loblolly pine seedlings – essentially a comparison of planting depth vs. root straightening priorities. Shallow planting regardless of taproot form can kill seedlings. A seedling that has a bent taproot but is planted deeply will have a higher probability of survival than a shallow planted seedling with a straight taproot. David B. South, Professor, School of Forestry and... Read More

Rotation-Age Results from a Loblolly Pine Spacing Trial

June 8, 2021 - Report provides cubic-foot volume yields for particular product definitions from a 25-year-old loblolly pine spacing trial and shows how closely, in the absence of thinning, total and merchantable wood production are linked to initial spacing. The results of this study suggest that no single planting density will be optimal for all management objectives. Ralph L. Amateis and Harold E. Burkhart.

Nine-Year Growth Responses to Planting Density Manipulation and Repeated Early Fertilization in a Loblolly Pine Stand in the Virginia Piedmont

June 8, 2021 - Report provides results of a study of two planting densities (363 and 726 trees per acre) and three levels of nutrient additions aimed at maintaining the current site index (SI25) of the stand (55 ft.) or improving the SI25 to 70 and 80 ft. None of the treatments affected survival or height during the first 9 years, but both affected diameter growth. Colleen A. Carlson, Thomas R. Fox, Jerre Creighton, Phillip... Read More
