Agroforestry practices may also promote mineral N fertilization and the use of N2-fixing legumes that favor the emission of non-CO2 greenhouse gases (GHG) (N2O and CH4). The present study evaluates the net GHG balance in two adjacent coffee plantations, both highly fertilized (250 kg N ha-1 year-1): a monoculture (CM) and a culture shaded by the N2-fixing legume tree species Inga densiflora (CIn). C stocks, soil N2O emissions and CH4 uptakes were measured during the first cycle of both plantations. During a 3-year period (6-9 years after the establishment of the systems), soil C in the upper 10 cm remained constant in the CIn plantation (+0.09 \u00b1 0.58 Mg C ha-1 year-1) and decreased slightly but not significantly in the CM plantation (-0.43 \u00b1 0.53 Mg C ha-1 year-1). Aboveground carbon stocks in the coffee monoculture and the agroforestry system amounted to 9.8 \u00b1 0.4 and 25.2 \u00b1 0.6 Mg C ha-1, respectively, at 7 years after establishment. C storage rate in the phytomass was more than twice as large in the CIn compared to the CM system (4.6 \u00b1 0.1 and 2.0 \u00b1 0.1 Mg C ha-1 year-1, respectively). Annual soil N2O emissions were 1.3 times larger in the CIn than in the CM plantation (5.8 \u00b1 0.5 and 4.3 \u00b1 0.3 kg N-N2O ha-1 year-1, respectively). The net GHG balance at the soil scale calculated from the changes in soil C stocks and N2O emissions, expressed in CO2 equivalent, was negative in both coffee plantations indicating that the soil was a net source of GHG. Nevertheless this balance was in favor of the agroforestry system. The net GHG balance at the plantation scale, which includes additionally C storage in the phytomass, was positive and about 4 times larger in the CIn (14.59 \u00b1 2.20 Mg CO2 eq ha-1 year-1) than in the CM plantation (3.83 \u00b1 1.98 Mg CO2 eq ha-1 year-1). Thus converting the coffee monoculture to the coffee agroforestry plantation shaded by the N2-fixing tree species I. densiflora would increase net atmospheric GHG removals by 10.76 \u00b1 2.96 Mg CO2 eq ha-1 year-1 during the first cycle of 8-9 years.", "keywords": ["P33 - Chimie et physique du sol", "570", "571", "[SDV]Life Sciences [q-bio]", "F08 - Syst\u00e8mes et modes de culture", "http://aims.fao.org/aos/agrovoc/c_1920", "stockage", "Funders: EU CASCA project", "http://aims.fao.org/aos/agrovoc/c_24345", "01 natural sciences", "630", "agroforestry", "leguminous tree", "soil organic matter", "http://aims.fao.org/aos/agrovoc/c_7427", "andosol", "gaz \u00e0 effet de serre", "http://aims.fao.org/aos/agrovoc/c_1721", "http://aims.fao.org/aos/agrovoc/c_34841", "http://aims.fao.org/aos/agrovoc/c_1666", "http://aims.fao.org/aos/agrovoc/c_1301", "Inga", "syst\u00e8me de culture", "http://aims.fao.org/aos/agrovoc/c_35657", "0105 earth and related environmental sciences", "agroforesterie", "2.
