Web6.3 Bulk Density Soil bulk density of Horizons A and B1 was measured at 348 points across 79 sites. Results are summarised in Tables 6.10 and 6.11. Horizon A of Groups 1, 2 and 3 has larger standard deviation compared to Horizon B1. For Groups 1, 2 and 3, bulk density of Horizon A has larger variability within group compared to those of Horizon B1.
