Fig. 3: POM distributions in soils under different fertilizations at five experiment sites.
From: Soil macropore structure plays divergent roles in fresh and decomposed particulate organic matter
Fresh POM (a) and decomposed POM (b). In surface-connected pores (green) and isolated pores or matrix (yellow). Different lowercase letters indicate significant differences among different fertilizations (P < 0.05). Vertical bars represent standard errors (n = 4).
