Species diversity (Shannon index), richness (Chao index), and coverage (Coverage index) soil samples for OTUs constructed at 0.03 dissimilarity for bacterial and fungal sequences.

	Sample	Shannon Index	Chao Index	Coverage Index
Bacteria	soil 1	2.97 ± 0.07 a	144.60 ± 62.58 a	0.18 ± 0.10 a
	soil 2	2.95 ± 0.01 a	131.00 ± 34.64 a	0.16 ± 0.01 a
	soil 3	2.92 ± 0.01 a	120.00 ± 40.99 a	0.20 ± 0.04 a
Fungi	soil 1	3.13 ± 0.22 a	515.43 ± 44.59 a	0.99 ± 0.00024 a
	soil 2	3.37 ± 0.04 a	542.99 ± 6.77 a	1.00 ± 0.00004 a
	soil 3	3.36 ± 0.02 a	528.37 ± 7.63 a	1.00 ± 0.00013 a

Note: data are represented as mean ± standard error (S.E.). Statistical analyses were performed with the Mann–Whitney U test between the two groups. The richness estimator (Chao), diversity estimator (Shannon), and coverage estimator (Coverage) were calculated at 3% distance. p < 0.05. Variants labeled with the same letters are not significantly different. Soils 1–3 stand for soil collected at three different spots from the same farm field.
