The bulk density of soil reflects the mass or weight of a certain volume of soil. Soil bulk density determines the infiltration, available water capacity, soil porosity, rooting depth/restrictions, soil microorganism activity, root proliferation, and nutrient availability.
Bulk density is the weight of soil in a given volume, and affects root growth, soil permeability and nutrient levels. Learn how to measure bulk density using different methods, and how to interpret the results for soil quality assessment.
In materials science, bulk density, also called apparent density, is a material property defined as the mass of the many particles of the material divided by the bulk volume.
1 Ιαν 2016 · Brady and Weil (2002) define bulk density as the mass (weight) of a unit volume of dry soil. Blake's (1965) definition states that this soil parameter is the ratio of the mass to the bulk, or microscopic volume of soil particles plus pore spaces in the sample.
24 Ιουν 2021 · Bulk density, particle density, and porosity are three soil physical properties exemplifying the relationships among the soil phases. The volume of voids in soil is related to the percentages of sand, silt and clay (soil texture) and to the arrangement of these soil particles soil structure.
24 Ιουν 2021 · Bulk density is the dry mass of a soil divided by the total soil volume. The bulk density value for soil is calculated using the formula: Bulk Density = mass (g) oven dry soil / total soil volume (cm 3 )
Oven-dry soil bulk density (for short, soil bulk density, or BD) is a key proxy of soil structure and compaction affecting nutrient pools and soil carbon stocks, which are strongly associated with atmospheric carbon dioxide and useful indicators of global changes (Fernández-Ugalde and Tóth, 2017).
