18. Entire Root System is Outplanted
• Elimination of root damage during lifting and packing
(fine roots and mycorrhizae remain intact)
• Uniform moisture surrounding roots throughout plug
• Eliminate occurrence of J-Rooting at outplanting

36. Langdale Property Test Planting
Purpose of Study
Compare early August planted container seedlings to winter planted bareroot using
different chemical treatments
Study Design
1. All plots were bedded.
2. Treatments were as follows:
A. Chopper applied on beds ahead of planting
B. DAP impregnated with Velpar was applied after planting
C. Control was bedding only
3. Container Seedlings planted August 21, 2000.
4. Bareroot Seedlings planted during winter 2000-2001.
5. Three rows of 20 seedlings each were planted of each container and
bareroot of each species of Loblolly, Slash, and Longleaf.
6. Only the middle row of 20 seedlings were measured.
7. Container seedlings were planted 2 weeks after chopper application and
seedlings showed poor to no root growth 60 days after planting. This had some
impact on survival in chopper treatments with container seedlings.
8. As evidenced by controls, both chemical treatments affected survival.
