英文摘要: A 2-year-long monitoring experiment was conducted to determine the effects of phosphorus (P) addition on nitrous oxide (N2O) emission, methane (CH4) uptake and carbon (C) sequestration and decomposition in a newly established Acacia mangium plantation in South Sumatra, Indonesia. We established three large plots and prepared six control sub-plots and four sub-plots with P added in each large plot. Gas emissions were measured using a chamber method. We also measured selected physical and chemical parameters for soil, fresh leaves, litter layers, and the aboveground biomass of Acacia trees. Mean daily N2O flux was reduced (0.42mgN m-2 day-1) by P addition. The reduction in N2O emissions resulting from P addition was likely to be due to the stimulation of root uptake of soil N and water, as suggested by the soil N and WFPS dynamics and correlations with N2O fluxes. P addition significantly increased (25.6Mgha-1 20months-1) the Acacia biomass, contributing to an increase (46.9Mg CO2-e ha-1) in C sequestration. P addition also stimulated soil C decomposition. Soil total C (TC) decreased significantly (0.14kgCm-2) in the second year of P addition; CO2 emissions from soil were also stimulated (0.29g C m-2 day-1) by P addition. P addition reduced (0.15mgC m-2 day-1) CH4 uptake significantly, although the difference was small. © 2013 Elsevier B.V. Citation statistics:
