Bulk Density - Measurement | Fact Sheets | soilquality.org.au

If soil has >10 % gravel or the stones are >2 cm conventional bulk density readings will be inaccurate, as most coarse fragments have bulk densities of 2.2–3.0 g/cm 3 (McKenzie et al., 2002). This is important to recognise when using bulk density measurements to calculate nutrient levels on an area basis, as an over-estimation will occur.

The bulk density is more in compacted state as compared to the loose which shows that the bulk density greatly depends on the degree of compaction or how densely it is packed. Usually increase in bulk density should be above 15% for coarse aggregate and should be below 15% for fine aggregate, But in our results it is 11.20% for fine aggregate and 11.48% for coarse aggregate.
