The effect of irrigation on the microbial communities’ structure and composition. a PCoA of Bray-Curtis distances for the nifH-based diazotrophs, showing the beta-diversity changes between irrigation treatments. Biplot shows the correlation of the two major Bradyrhizobium species with the samples. Statistical significance of the irrigation effect using MRPP is shown. b PCoA of the cross K-functions (CKF) derived from K-Shuff for the 16S rRNA genes. The plot highlights a separation between the samples based on the irrigation treatment, as delineated by the dashed line. K-Shuff statistical testing revealed a significant effect for all experimental factors (p value = 0.001)
