Effects of Legume‒Cereal Rotation on Sorghum Rhizosphere Microbial Community Structure and Nitrogen-Cycling Functions.

ABSTRACT: Legumes form mutualistic interactions with specific soil microbiomes that fix atmospheric nitrogen and improve soil fertility. However, legume-based rotations influence on soil microorganisms and their correlations with soil physicochemical parameters during subsequent crop development are not yet clear. We examined the shifts in microbial community structure and nitrogen genes via shotgun sequencing across cowpea-sorghum, soybean-sorghum, maize-sorghum rotations, and sorghum without precrops. Precropping in rotation significantly affected N-NO₃, clay, and silt, and caused a shift in the rhizosphere microbiome. Actinomycetota was the most predominant bacteria across all the cropping systems, followed by Pseudomonadota, whose composition differed across the cropping systems. Legu
