Mean final bulk density at different soil depths for compacted and uncompacted soils. Means in the same row or column with a different letter are significantly different (P < 0.05).
| Depth | Uncompacted Mg/m−3 | Compacted Mg/m−3 |
|---|---|---|
| Top (0-10 cm) | 1.50a | 1.60bc |
| Middle (10-20 cm) | 1.54b | 1.58 |
| Bottom (20-30 cm) | 1.55c | 1.57 |
