  • Bulk density Wikipedia

    The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction. The density of quartz is around 2.65 g/cm but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm . In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm ) due to a combination of the low-density of the organic materials themselves and increased porosity. For instance, peat soils have bulk densities from 0.02 to 0.98 g/cm .
