Alpha diversity indices (Shannon diversity (A, B, C, D, E, F), Chao1 index (G, H, I, J, K, L), and Pielou’s evenness (M, N, O, P, Q, R)) of soil bacterial and fungal amplicon sequencing variants (ASVs) in topsoil and subsoil of an agrosilvopastoral and syntropic alley cropping system near Alt Madlitz, Germany (n = 6). Dots indicate individual data points. Different letters indicate statistically significant differences among the six sampling locations within the agrosilvopastoral alley cropping system (ANOVA followed by Tukey’s HSD test; p ≤ 0.05). Asterisks indicate statistically significant differences between the two soil depths across sampling locations (linear mixed effect models; p ≤ 0.05) as well as the two sampling locations within the syntropic alley cropping system (Student’s t-test; p ≤ 0.05). Absence of letters or asterisks indicates no statistically significant differences between soil depths or sampling locations (p > 0.05). Icons were created with BioRender.com.
