Effects of Five Silvicultural Treatments on Loblolly Pine in the Georgia Piedmont at Age 20

Age 20data from a designed experir7zental study installed on 24plorsat one location in the Lower Piediizont in Jones County, Georgia, tilere used to evaluate the effect of six silviculrural treatments on survival, growth, and yield of cutover site-pi-epared lobloll~1 pine plantations in the Georgia Piedmont. The following silvicultural treatnzeizts were included in the study: ( I ) clearcut only, (2 ) clearcut with all residual treesgreater than I inch dbh removed by chairzsn~~, (3) slzear and chop, (4) shear, rootrake, burn, and disk, and (5) shear, rootrake, burn, disk, fertilize, and herbicide. Treatment sigizificanrly affected all tree aizd stand characteristics at age 20. The slzear, rootrake, burn, disk, fertilize, and herbicide rrearnlent ranked best in all categories with the exception ofsuwival aizd basal area, which were Izighestfor the shear, rootrake, burn, and disk treatmenr. The shear and chop trearrnent was 1701 sigizifcanrly lower rlzan the ~izost intensive treatment in any measured category. Sourh. J . Appl. For. 28(1):35-40.
