|---|---|---|---|
| TN (%) | 0.132 ± 0.001b | 0.124 ± 0.002c | 0.135 ± 0.00a |
| TP (%) | 0.12 ± 0.001b | 0.12 ± 0.00b | 0.20 ± 0.004a |
| AP (mg/kg) | 55.1 ± 0.08b | 33 ± 0.08c | 68.1 ± 0.05a |
| AK (mg/kg) | 117 ± 0.16b | 92.76 ± 0.03c | 118.1 ± 0.05a |
| TK (g/kg) | 16.1 ± 0.02b | 17.1 ± 0.05a | 17.1 ± 0.04a |
| PH | 8.05 ± 0.04a | 8.06 ± 0.05a | 8.03 ± 0.07a |
| SOM (g/kg) | 17.95 ± 0.11a | 18.04 ± 0.1a | 17.96 ± 0.32a |
Values are means ± standard deviation (n = 3). Means followed by the same letter for a given factor are not significantly different (P < 0.01) according to one-way analysis of variance (ANOVA).
