摘要： Calcium (Ca) contributes to soil organic carbon (SOC) sequestration and stabilization through physical and chemical protection. Yet, how long-term Ca addition affects microbial- and plant-derived C and the influencing factors remained unclear. We determined the contents of amino sugars and lignin phenols to explore the effects of Ca addition on microbial- and plant-derived C during a 36-year long-term field experiment under NPK and NPK+Ca fertilization regimes in red soils (0–10, 10–20, and 20–40 cm soil layers) in southern China. The combination of NPK and Ca fertilization reduced plant-derived C (lignin phenols) content by 39 % and its proportion to SOC by 25 % in 0–10 cm soils, which explained a lower SOC content compared to NPK treatment. The reduction in plant-derived C was primarily attributed to the declines in enzyme activities for plant litter transformation and iron (Fe) oxides content for SOC adsorption. In contrast, microbial necromass C content remained constant in 0–40 cm soils under NPK+Ca fertilization, which was a result of the offset of the increased Ca-OC and decreased Fe-OC, indicating mineral shifts and interactions of Ca-Fe-OC complexes. Taken together, this study provides direct evidence for the effects of long-term Ca fertilization on plant-and microbial-derived C sequestration via mediating organo-minerals associations in acid soils.
