Fig. 4From: Interactions between rootstocks and compost influence the active rhizosphere bacterial communities in citrusRelationships between bacterial alpha A and beta B diversity and the multinutrient cycling index (MNC) for each rootstock and treatment. The bacterial α-diversity was calculated as the average value of the Shannon index after minimum-maximum normalization. The microbial community composition (β-diversity) was estimated using the first axis of the nonmetric multidimensional scaling (NMDS) analysis. Solid lines denote significant Pearson correlations (p ≤ 0.05)Back to article page
