Soil acidification and carbon sequestration are central issues in addressing global soil degradation and climate change. Soil acidification, driven by natural processes and human activities, has significant negative impacts on soil physicochemical properties, agricultural productivity, and ecosystem functions. In contrast, soil carbon sequestration, as a critical approach to mitigating climate change, not only enhances soil fertility but also improves ecosystem functionality. This paper systematically outlines the mechanisms underlying soil acidification and its effects on soil properties and the environment, while delving into the processes and influencing factors of soil carbon sequestration. It emphasizes the evaluation of major technologies for ameliorating acidic soils, including traditional lime amendments, novel materials such as biochar, and biological approaches. The paper also highlights the application of carbon sequestration techniques in improving acidic soils, such as optimizing agricultural management, applying amendments, and promoting vegetation restoration. By analyzing the synergistic mechanisms between acidic soil amelioration and carbon sequestration technologies, it elucidates how these approaches effectively enhance soil carbon stocks and overall soil health. Finally, the paper identifies the limitations of existing research and challenges in technology adoption, proposes future research directions and critical breakthroughs, and envisions the broad prospects of integrated technical applications. This paper aims to provide a theoretical foundation and technical reference for synergistic research on acidic soil amelioration and carbon sequestration, fostering scientific progress and practical applications in this field.
