Abstract :

Forest biomass is used for renewable energy and it also plays a significant role in soil nutrients, to influence soil respiration. This study was conducted to investigate the rate of soil respiration from a recovering forest biomass of the tropics and its relationship to changes in the environmental factors after years of deforestation. Soil respiration measurement was conducted using the continuous open flow chamber technique connected to a multi gas-handling unit and infrared gas analyser while the forest biomass and soil properties were directly measured and further quantified using the Kjeldahl method and Walkleyblack wet oxidation technique. The average mean soil respiration rates were 341.23, 383.07, 340.30, 308.12, 286.07, 256.05 mg m-2 h-1 between June and December and the recovering forest biomass was found to host an estimated Total Above Ground Biomass (TAGB), Below Ground Biomass (BGB), Soil Organic Carbon (SOC) and Soil Organic Carbon stock (SOC stock) of 1.8 x 103, 1.0 x 103, 2.4 x 103 mg and 52.28 mg ha-1 respectively. Soil respiration exhibited a variation pattern that was similar to soil temperature pattern and the occurrences of forest carbon input from biomass and soil properties as they were found to be significantly correlated with soil respiration to provide nutrients for microorganism to emit soil CO2. The remarkable soil CO2 emission from the recovering forest biomass was attributed to changes in environmental factors as the forest was recovering from deforestation. The correlation and multiple regression model proved forest biomass and environmental factors to influence the high rate of soil CO2 emission, indicating a strong positive relationship (0.94; p<0.01). These results suggest that, forest recovering could still emit considerable percentages of soil CO2 due to impact from deforestation, which could have a great implication on environmental factors and the atmospheric carbon balance.
