The presence of soil compaction and root-restricting layers (e.g., plow pans) resulting from long-term agricultural practices often poses difficulties when converting these sites into loblolly pine plantations. Subsoiling is usually prescribed to alleviate any problems with soil strength. Subsoiling also creates soil conditions that may aid or hinder planting seedlings. The interaction of planting location. either in the furrow or the adjacent 0.3. 0.9 or 1.5 ft, and planting depth on 2 marginal crop lands was assessed in this study. Planting seedlings in the furrow and deep planting (to the terminal bud) resulted in better growth and increased survival after the first growing season compared to planting outside the furrow and shallow to moderately deep planting. respectively
