Wet Density is a measure of soil and water, in a given volume.

​

Dry Density is a measure of the dry soil only, in a given volume.

 

Example:

​

You have a 1 litre mould with 2204 grams of wet soil in it,

​

​

​

​

​

​

​

If the moisture content of that soil is 12.3% (w), you need to calculate the moisture out, so you’re left with dry soil only.
