One method for determining bulk density is by pounding a ring into the soil of a known volume and then determining the mass of dry soil. A soil core sampler is frequently used to pound the ring into the soil. An example of a slide hammer device that is used to collect samples to measure soil bulk density can be seen in Figure 1. After cores are ...
