Taxonomic and functional diversity of the soil microbiome recruited from alternative crops in a rotation system

Abstract Intensive cropping is considered to contribute negative effects both on soil physiochemical properties and long‐term grain yield, which can be alleviated by appropriate crop rotations. Soil microbial community vary with different rotations, in turn affect quality yield. Therefore, it of great significance elucidate the response rotation. In this study, structural functional changes rotations were analyzed using high‐throughput sequencing metagenomics analysis a field experiment. The continuous winter wheat‐summer maize system was control three established October 2016 as follow: (1) spring peanut→winter maize, (2) (3) sweet potato→winter maize. samples collected September 2021 for assessment. results showed that relative abundance Actinobacteriota significantly higher (15.2%) than setup. Ascomycota (19.8–23.2%) following rotation compared Compared setup, enriched energy metabolism genes, reduced genes related plant‐pathogen interaction. control, decreased inorganic P solubilization gene ( gcd ) phosphorus transport upgE increased organic mineralization phoA phyA ). Based these results, we concluded composition altered rotation, had more significant effects.
