Abstract

Macropores resulting from soil pedogenesis, biological activity, and agricultural practices play important roles in soil water, chemical and gas transport; however, seldom studies focus on the effect of soil macropores on CO2 behavior. In this study, a 150-day soil column incubation experiment was conducted to investigate the CO2 behavior in a homogeneous soil column and a soil column with an artificial macropore, which have the same total porosity. The results showed that the cumulative CO2 fluxes observed in the soil with a macropore (57.2 g m−2) were higher than those in the homogeneous soil (52.7 g m−2). The soil cumulative CO2 fluxes measured using column incubation can fit the kinetic model, and a higher carbon mineralization rate in the soil with the macropore was found. The results of the incubation experiment also suggest that macropore increased the gas diffusivities, and thus decreased the CO2 concentrations in the soil profile. This study proposed a simulation experiment and quantified the effect of macropore on soil CO2 behavior, which could help to understand the mechanism of CO2 emission from soil with macropores especially caused by agricultural practices.
