Understanding the response of soil properties and microbial communities under crop rotation is essential for the sustainability of agroecosystems. However, limited research has focused on crop rotation altering the below-ground microbial communities in these soils with serious bacterial wilt in the karst agricultural system. This study investigated the effect of continuous planting of corn, tobacco, and tobacco-corn rotation on soil microbial communities in the karst areas of southwest China. High-throughput sequencing were used to evaluate the responses of soil microbial community structure to crop monoculture and rotation patterns. As expected, Tobacco-corn rotation mitigated the negative effects of continuous cropping and attenuated the trend of soil acidification. Tobacco-corn rotation also significantly altered the microbial communities and promoted plant growth through enrichment of more beneficial microorganisms. The predominant bacteria genera of Sphingomonas and Gaiellales, and predominant fungal genera of Mortierella and Saitozyma were assumed as discriminant biomarker genera and critical to soil ecosystem health. pH, AK and AP were the primary soil factors related to the soil microbiome assembly. This study demonstrated the associations between crop rotation and microbiomes, opening the possibility of manipulating cultivation patterns to develop the karst agricultural systems.
