# Wet bulk density of soil (total bulk density)

## Description

Bulk density is a property of powders, granules, and other “divided” solids, especially used in reference to mineral components (soil, gravel), chemical substances, (pharmaceutical) ingredients, foodstuff, or any other masses of corpuscular or particulate matter. It is defined as the mass of many particles of the material divided by the total volume they occupy. The total volume includes particle volume, inter-particle void volume, and internal pore volume.

The bulk density of soil depends greatly on the mineral make up of soil and the degree of compaction. Bulk density of soil is usually determined from a core sample which is taken by driving a metal corer into the soil at the desired depth and horizon. This gives a soil sample of known total volume. From this sample the wet bulk density and the dry bulk density can be determined.

Wet bulk density is the total mass of soil (soil plus liquids) vs the volume as a whole
