Carbon dioxide (CO2) is a major greenhouse gas (GHG) contributing about 60% to the total GHGs in the atmosphere. According to statistics, 70% of the earth soils are waterlogged soil (reduce condition) which has effect on CO2 fluxes. Hence, the experiment set out is to investigate how CO2 is being emitted under different soil redox potential. Three locations were used for the study. The sites were categorized into Oxidized soil (Eh> 300), moderately reduced soil (-100 to 300) and reduced soil (redox Eh< - 100). Data collected included the emissions of CO2 on each of the redox statuses. CO2 emission was monitored using gas entrapment method and it was done in the morning, afternoon and evening. Also cumulative trapping was done for 24 hours. Graph and bar chart were generated using Microsoft excel 2016 to present results. The result showed that the emission of CO2 is highest under Oxidized soil and low in moderately reduced soil and reduced soil. Also emission was found to be highest in the afternoon compared to other times of the day. It was concluded that there is emission of CO2 in the three locations however; Oxidized soil has the highest emission of carbon dioxide.
