Bulk Density - Measurement Fact Sheets soilquality.org.au

Bulk density is the weight of soil in a given volume. Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. Bulk density increases with compaction and tends to increase with depth. Sandy soils are more prone to high bulk density. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).
