Fig. 3From: Effects of marine sediment as agricultural substrate on soil microbial diversity: an amplicon sequencing studyBoxplots of alpha diversity metrics (Observed OTUs, Evenness, and Shannon index) used to study the metagenomic of lemon production soil samples. The results highlighted in red indicate significant differences between experimental groups according to the Kruskal-Wallis and post-hoc tests (two-by-two comparisons controlling for significance)Back to article page
