摘要 | A temperature stepped-combustion method for separating soil organic carbon (SOC) fractions and their C-14 ages was developed to investigate SOC fixation and stability in soils. After acid-leaching, SOC was sequentially oxidized, and extracted from three temperature intervals: (1) 25-400 degrees C, (2) 400-600 degrees C, and (3) 600-900 degrees C. The acid-soluble carbon and SOC released below 600 degrees C are labile components, with relatively younger C-14 ages, while the SOC released above 600 degrees C is stable with older C-14 ages. We applied this method in a grassland, maize cropland and forest nursery cropland, to assist in understanding the stability of carbon in soils under different land use conditions. |
