Dry Bulk Density of Soil

on . Posted in Geotechnical Engineering

partially saturated soil 1Dry bulk density of soil, abbreviated as \(Y_{dry}\), is a measure of the mass of dry soil per unit volume.  It is commonly used in soil science, agriculture, geology, and engineering to characterize and classify soils.

Bulk density is an important parameter in soil analysis because it provides information about the compactness and porosity of soil, which can influence its ability to hold and transport water, nutrients, and air.  Different soils will have different bulk densities based on their composition and structure.  Soil scientists and engineers use bulk density measurements to assess soil quality, determine soil compaction levels, and make decisions about land use and agricultural practices.  It can also be a valuable parameter for assessing soil erosion and land degradation.


Dry bulk density of soil formula

\( Y_{dry} = M_s \;/\; V_t \)     (Dry Bulk Density of Soil)

\( M_s =  Y_{dry} \; V_t  \)

\( V_t =  M_s \;/\; Y_{dry} \)

Symbol English Metric
\( Y_{dry} \) = dry bulk density of soil \(lbm \;/\;ft^3\) \(kg \;/\; m^3\)
\( M_s \) = mass of soil \(lbm\) \(kg\)
\( V_t \) = total volume of soil \(ft^3\) \(m^3\)
