Soil arbuscular mycorrhizal fungal hyphal length and phospholipid fatty acid (PLFA) biomass in different soil layers under mycorrhiza inoculation treatments and the control (mean ± SD; n = 3).

	Hyphal length	PLFA biomass
Control	ND	1.09 ± 0.09 ab
AM-L1	3.27 ± 0.40 a	1.57 ± 0.28 c
AM-L2	3.24 ± 0.26 a	1.26 ± 0.15 bc
AM-L3	2.71 ± 0.23 a	0.91 ± 0.10 ab
AM-L4	1.77 ± 0.47 b	0.81 ± 0.22 a

Different lowercase letters in the same column indicate significant differences between the control and different soil layers by Duncan’s multiple range test at P < 0.05.
