TABLE 1.
Bacterial community alpha diversity indexes across season.
| Season | 2015 | 2016 | ||
| Observed | Shannon | Observed | Shannon | |
| Spring | 1071 a | 4.42 a | 1030 a | 4.61a |
| Mid | 799 b | 4.20 b | 1039 a | 4.26b |
| Fall | 1052 a | 4.49 a | 1034 a | 4.61a |
| ANOVA: | ||||
| CropSeq | <0.001∗∗∗ | <0.001∗∗∗ | 0.86 | 0.060 |
| Season | <0.001∗∗∗ | <0.001∗∗∗ | 0.99 | 0.002∗∗ |
| CropSeq∗season | 0.14 | 0.4 | 0.52 | 0.006∗∗ |
The data are means across all 40 samples, 10 crop sequences each with four replicates within each season. Significant differences are reported at (.) P < 0.1, (∗) P < 0.05, (∗∗) P < 0.01, and (∗∗∗) P < 0.001. Different letters in a column indicate a significant difference between seasons according to the Least Significant Difference (LSD) test at P < 0.05.
