Temporal variability of the CO2 emission and the O2 influx in a tropical soil in contrasting coverage conditions

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. 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). 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
