Conteúdo: 	Abstract: Integrated systems have practices and alternatives aligned with the purpose of greenhouse gas (GHG) mitigation, and knowing the spatial and temporal variability of soil gas fluxes is the first step toward understanding how integrated systems mitigate GHG emissions. This work aims to assess the spatial and temporal distribution of the GHG fluxes of soils cultivated with soybean and corn in integrated systems with trees in Brazil, southern Amazonia. Soil GHG fluxes were measured using static chambers during the whole cycle of soybean and corn cultivation in the integrated system. The trees formed alleys of triple rows of eucalyptus, with 30 m intervals between the alleys. Soybean and corn were successively cultivated in the space between the alleys. The spatial and temporal distribution of the GHG fluxes showed that the nitrous oxide (N2O) and methane (CH4) fluxes were highly related to soil management factors, such as fertilization and soil use. As the carbon dioxide (CO2) fluxes showed a largely similar distribution among the points within the same sampling date, another condition similar across all points (such as precipitation) could be influencing the decomposition of the soil organic matter and root respiration, which are the main processes responsible for CO2 production in soils.
