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).

Bulk density, ρ, is the ratio of sample mass to sample volume for a dry sample. Bulk density can be calculated from the particle density (dry mass of all solid particles in a sample divided by the volume of those solid particles) or the specific weight of a dry soil given the sample porosity. Bulk density or sample volume is needed to convert
