Radial stem wood sections of fertilized (at age 14 years) and unfertilized loblolly pine (Pinustaecla L.) trees were analyzed 5 and 9 years after treatment to establish if xylem nitrogen (N) can be used for a diagnostic nitrogen test. The percentage of xylem nitrogen in wood formed since fertilization was greater in fertilized than in unfertilized trees. The 2 years of wood growth near the cambium had a higher percent N than older wood, but differences between treatments were less pronounced than in older wood. Concentrations of N for fertilized and unfertilized trees were nearly constant for 2- to 9-year-old wood indicating that a sampling technique to determine the N status of loblolly pine could be developed by increment coring.
