AbstractNitrogen (N) and phosphorus (P) fertilization are effective methods for increasing forest productivity and have been widely used in the management of forest plantations. However, how changes in the N:P ratio affect the sequestration of carbon in forests is unclear. We measured the net primary production (NPP) based on plot inventory, soil respiration (R-S), autotrophic respiration (R-A), and heterotrophic respiration (R-H) using static chamber with GC method after trenching to compare the effects of low N fertilization (50 kg N ha(-1) year(-1)), high N fertilization (100 kg N ha(-1) year(-1)), P fertilization (50 kg P ha(-1) year(-1)), low N plus P fertilization, high N plus P fertilization, and an unfertilized control on net ecosystem productivity (NEP). The NEP was significantly higher with 39-60% more under N and P fertilization than that of control. However, the mechanisms contributing to the difference varied among different treatments. Specifically, the R-H was unchanged with P fertilization but significantly lower with N fertilization, while NPP was significantly higher with P or N fertilization. The NEP was higher with N plus P fertilization than with either N or P fertilization, although the interactive effect was not significant. Our findings suggested that P fertilization may be an effective method of improving timber yield and that adding both N and P fertilizers at a higher ratio may favor ecosystem carbon sequestration in P-limited stands.
