Fig. 2: Carbon (C) content in mineral associated organic matter (MAOM) according to treatment and sampling time.
From: Alive and dead earthworms capture carbon during mineral weathering through different pathways
Values are expressed as mg C·g-1 organo-mineral mixture. Values represent the mean and the bars the standard error for four independent replicates. Different letters indicate significant differences between treatments (P < 0.05). Statistical significance was analysed using ANOVA followed by a post hoc Tukey’s test. B1 = treatment with basanite after 60 days; B2= treatment with basanite after 120 days; BP1 = treatment with basanite and pea straw after 60 days, BP2= treatment with basanite and pea straw after 120 days; BPEa1 = treatment with basanite, pea straw and earthworms added alive after 60 days; BPEa2= treatment with basanite, pea straw and earthworms added alive after 120 days; BPEd1 = treatment with basanite, pea straw and earthworms added dead after 60 days; BPEd2= treatment with basanite, pea straw and earthworms added dead after 120 days.
