Consortium for Accelerated Pine Production Studies (CAPPS): Long-term Trends in Loblolly Pine Stand Productivity and Characteristics In Georgia

Abstract

Beginning in 1987, a series of long-term study plots were installed to determine the effects of annual nitrogen fertilization and complete control of competing vegetation on loblolly pine (Pinus taeda L.) stand growth and development. The study had two locations, one at the Dixon State Forest (DSF) near Waycross, GA on the lower coastal plain and the other at the B.F.Grant Experimental Forest (BFG) near Eatonton, GA on the Piedmont. The Dixon State Forest is characterized by long, hot, humid summers, with an average maximum July temperature of 33°C, and winters that are cool and fairly short, with an average January low temperature of 2.6°C. Average annual precipitation is about 130 cm, with about 60 percent falling between April and September. Soils are spodosols or ultisols that are arenic or grossarenic with slopes < 1 percent. The B. F. Grant location is characterized by warm to hot summers, with average July high temperature of 33°C, and moderately cold but highly variable winters, with average January low temperature of 2.2°C. Average annual precipitation is about 120 cm, with a maximum in early spring, a minimum in fall, and fairly even distribution for the rest of the year. Soils are clayey ultisols with slopes < 15 percent. Within each location there were two study sites separated by less than 6 kilometers.
