#### What is Bulk Density? - Definition from MaximumYield

Determining the bulk density of your particular soil is done by taking a core sample, drying the sample thoroughly (often in an oven or kiln), and then weighing it. Prior to drying, the sample should be weighed as well to determine the wet bulk density in order to compare that to the dry density.
