Fig. 4From: Influence of tree species on soil microbial residue accumulation and distribution among soil aggregates in subtropical plantations of ChinaDistribution of microbial residues among aggregates in 0–20 cm soil layer of different tree species. Different lowercase letters indicate significant differences among tree species (p < 0.05). LMA large macro-aggregates, SMA small macro-aggregates, MA micro-aggregatesBack to article page
