Descrição: dc.descriptionAim: The proposal was to investigate the temporal variability of CO2 emission (FCO2), the influx of O2 in the soil (FO2), soil moisture (SM) and soil temperature (ST), as well as, understand the process of oxygen entry into the soil. Methods: Soil and its relationship with land cover and local climatic conditions. FCO2, FO2, soil moisture and temperature, and other meteorological data (e.g., atmospheric pressure, average air temperature and precipitation). Results: There was a positive linear correlation between the soil's CO2 emission and O2 capture and these correlations occurred in areas of mulch and vegetated cover, respectively, r = 0.45 (p < 0.05) and r = 0.44 (p < 0.05). The analysis of variance of temporal variability was significant, which demonstrates that the time and soil cover factors interfere with the dynamics of FCO2 (F = 2.1379; p < 0.0001), FO2 (F = 1.9124; p = 0.003), SM (F = 5.30; p < 0.0001), ST (F = 10.51; p < 0.0001). Conclusion: It is concluded that the temporal variability of the soil's CO2 emission and O2 capture is associated with the coverage, soil moisture and atmospheric conditions of the region. Thus, the soil cover provided thermal control and the maintenance of soil moisture. It is hoped that these contributions will serve as an interest in the formation of public policies for the mitigation of greenhouse gases, talking with the objective for sustainable development number 13.-
