Artificial grassland establishment alters soil organic carbon fractions and cbbL-type carbon-sequestering microbial communities
Mantel tests identified soil pH, the proportions of soil aggregates (>2 mm, 2-0.25 mm, and <0.053 mm), electrical conductivity, and MAOC content as the key environmental factors shaping the carbon-fixing microbial community. These results demonstrate that the establishment of artificial grasslands, particularly leguminous types, enhances the potential for soil carbon sequestration by modulating key soil properties and enriching specific carbon-fixing microbial taxa. This study provides a scientific basis for using artificial grasslands to enhance ecological restoration and soil carbon sequestration in arid regions.
