Influence of soil-water content on CO2 efflux within the elevation transect heavily impacted by erosion
Original language description
This study focused on the effects of organic carbon contents and soil-hydraulic conditions on CO2 efflux. Samples were collected at 5 positions (summit, shoulder, backslope, footslope andtoeslope) of the elevation transect affected by erosion and the parent material (loess). Initially, air-dried soil samples were placed on top of a clay tank and the samples were wetted by capillary rise to soil saturation, and soil CO2 efflux was measured. Numerical inversions of the measured cumulative capillary rise and evaporation data using the HYDRUS-1D program were applied to simulate the water regime in the columns and estimate the soil hydraulic parameters. In all cases, the net CO2 efflux (NCER) rapidly increased at the beginning of the wetting. NCER decreased with increasing soil-water content (summit, shoulder, backslope, and loess) or remained relatively stable (footslope and toeslope). The average soil-water content values at the maximal values of NCER for the summit, shoulder and footslope were similar.
