  • Bulk density - Wikipedia

    OverviewSoilSee alsoExternal links

    The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction. The density of quartzis around 2.65 g/cm³ but the (dry) bulk density of a mineral soil is normally about half that density, between 1.0 and 1.6 g/cm³. In contrast, soils rich in soil organic carbon and some friable clays tend to have lower bulk densities (<1.0 g/cm³) 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 g/c

Soils with a bulk density higher than 1.6 g/cm3 tend to restrict root growth. 3. Bulk density increases with compaction and tends to increase with depth. 4. Sandy soils are more prone to high bulk density. 5. Bulk density can be used to calculate soil properties per unit area (e.g. kg/ha).在soilquality.org.au上查看更多信息

  • Soil compaction UMN Extension

    Soil compaction changes pore space size, distribution and soil strength. One way to quantify the change is by measuring the bulk density. As the pore space decreases within a soil, the bulk density increases. Soils with a higher percentage of clay and silt, which naturally have more pore space, have a lower bulk density than sandier soils.
