Economics of Site Preparation and Release Treatments Using Herbicides in Central Georgia
Land expectation values (LEV) of site preparation and release treatments using herbicides in central Georgia are calculated and compared. Loblolly pine growth and hardwood competition levels were measured at age 6 for the site preparation treatments and age 8 for the release treatments. These measurements were projected to final harvest using the North Carolina State University growth and yield simulator. On six directly comparable sites, site preparation improved land expectation values more than release. When the most profitable treatments on each site were compared, site preparation LEVs (after tax) were more than twice as profitable as release ($403 vs. $188/ac). Velpar L¹ and Pronone 10G herbicide treatments increased the land expectation value most for site preparation. Arsenal AC and Velpar L provided the highest returns among the herbicides tested for release. South. J. Appl. For. 22(3):156-162.
