Ice damage effects on an old-field, thinned and fertilized loblolly pine stand in South CarolinaThis article is part of a larger document. View the larger document here.
On January 26, 2004, an ice storm impacted 15 South Carolina counties. An established fertilization study area in Clarendon County, SC, was in the affected region. This old-field, thinned, loblolly pine (Pinus taeda L.) stand was fertilized in the spring of 1998. Treatments consisted of: (1) control; (2) poultry litter (7 tons acre-1); and (3) diammonium phosphate (DAP) (125 pounds acre-1) and urea (385 pounds acre-1). Tree ice damage was measured six growing seasons after fertilization. Total numbers of trees damaged and severity of that damage was determined for each treatment 5 weeks after the storm. Percentage of total trees damaged was not significantly different between the treatments (p=0.1373), with a mean damage percentage of 37 percent for the control, 39 percent for poultry litter, and 45 percent for inorganic fertilizer. Percentage of severely damaged trees was also not significantly different (p=0.9684), with means of 2.0 percent for the control, 2.0 percent for broiler litter, and 2.3 percent for inorganic fertilizer.
