Descripción : Nitrous oxide (N2O) is a potent greenhouse gas and its emissions from soils contribute to climate change. Denitrification is one of the main microbial processes that yield N2O production in soils. N2O emission rates are mainly controlled by levels of NO3-, C, and O2. Soil pore structure has a tremendousinfluence on O2 and water distribution and therefore microbial activity. To date, there are no studies related to the Investigation of the influence of soil pore network as quantified by computed tomography (CT) on the denitrification-derived N2O emissions. In that regard, we purposed i) to create soil pore structure variation over different treatments by a combination of two bulk densities (BD) and three particle size distributions; and, ii) to determine the influence of the pore network structure on N2O emissions derived from denitrification. For this purpose, an incubation experiment with two bulk densities (1.35 and 1.50 g cm-3) and three particle size distributions 60:10:35, 35:35:30, and 10:60:30 (coarse sand (CS; 200 – 2000 μm), fine sand (FS; 53 -200 μm), and silt + clay (SC; <53 μm)
