Decomposition and Soil CO2 Emission

Back to Search Results

Students investigate the factors that control the rate at which CO2 is emitted from soil using simple soil chambers and soda lime in a field experiment. Students in small groups design and conduct their own experiments to investigate the effects of soil and microclimate factors on CO2 emission. The projects are typically conducted over two consecutive lab periods. During the first session students design their experiment and initiate their incubations. The incubation is ended after 24 to 48 hours and during the following lab period the final results are collected, the data are statistically analyzed, and a lab report is written as homework.
