Initial and final bulk density means for compacted and uncompacted soils. When comparing the same level of compaction, LSD = 0.08. Bulk density means in the same row or column with a different letter are significantly different (P < 0.05).
| Bulk density | Bulk density compacted Mg/m−3 | Bulk density uncompacted Mg/m−3 | LSD | P-value | Penetrative resistance compacted MPa | Penetrative resistance uncompacted MPa |
