In the context of global efforts to reduce carbon (C) emissions, several studies have examined the effects of agricultural practices such as straw returning and fertilization on C sequestration by microorganisms. However, our understanding of the specific microbial groups and their roles in long-term C increase remains limited. In this study, a 36-year (1984–2020) farmland experiment was conducted to investigate the impact of bacterial C metabolism on the augmentation of organic C in a Typic Hapludoll (Mollisol) in the black soil region of Jilin Province, Northeast China. Our results demonstrated a noteworthy increase in the diversity of microorganisms in the farmland as a result of long-term straw returning and application of mixed chemical fertilizers. However,by examining the functions of microorganisms involved in C metabolism, it was observed that the effects of fertilization on C metabolism were relatively consistent. This consistency was attributed to a deterministic competitive exclusion process, which minimized the differences between treatment groups. On the other hand, the influence of straw addition on C metabolism appeared to follow a more random pattern. These changes in microbial activity were closely linked to the downregulation of core metabolic pathways related to C metabolism. Notably, long-term fertilization had a negative impact on soil organic C levels, while long-term straw returning plus fertilization resulted in a positive increase in soil organic C. These findings have important implications for enhancing soil organic C and grain yield in the regions with typical black soil.
