Compound biofertilizers could improve the nutrient condition of the ecosystem and the fertility of agricultural fields. At micro level, the soil microbial communities could be influenced, resulting in taxonomic and functional changes in the soil microbiome. In the present research, compound biofertilizers were applied into tobacco (Nocotiana tabacum L., Family: Solanaceae) field ecosystems of Qianxi, Weining, and Meitan city of China, and the diversity of microbial communities were determined using metagenome technique. The results revealed that nitrogen compounds of each treatment were significantly increased after 30 d. In addition, indigenous microorganisms in fertilizer were developed into the dominant bacteria, and Compound Biofertilizer III has a potential and great effect compared with others. Depending on our findings, the research‐based knowledge obtained between compound biofertilizers, and soil microbiome could provide a clue to the development of environmentally friendly and long‐acting biofertilizer application processes in the agricultural fields.
