TABLE 2.

Bacterial diversity indices and estimated bacterial OTUs of soil samples collected from three ditches.

Ditches	OTU	Ace	Chao	Shannon	Simpson
DY	911 ± 119a	1235 ± 47.6a	1202 ± 50.2a	6.12 ± 0.03a	0.0045 ± 0.0003c
DZ	1060 ± 131a	1293 ± 68.6a	1257 ± 34.9a	6.057 ± 0.036a	0.0058 ± 0.0004b
DS	823 ± 107a	1192 ± 33.1a	1178 ± 47.17a	5.81 ± 0.03b	0.0074 ± 0.0004a

Different letters in the same column indicate that the differences between soil samples are significant at p < 0.05.
